  • Reactions of Aromatic Compounds Just Like an Alkene, Benzene Has Clouds of  Electrons Above and Below Its Sigma Bond Framework
    Reactions of Aromatic Compounds Just like an alkene, benzene has clouds of electrons above and below its sigma bond framework. Although the electrons are in a stable aromatic system, they are still available for reaction with strong electrophiles. This generates a carbocation which is resonance stabilized (but not aromatic). This cation is called a sigma complex because the electrophile is joined to the benzene ring through a new sigma bond. The sigma complex (also called an arenium ion) is not aromatic since it contains an sp3 carbon (which disrupts the required loop of p orbitals). Ch17 Reactions of Aromatic Compounds (landscape).docx Page1 The loss of aromaticity required to form the sigma complex explains the highly endothermic nature of the first step. (That is why we require strong electrophiles for reaction). The sigma complex wishes to regain its aromaticity, and it may do so by either a reversal of the first step (i.e. regenerate the starting material) or by loss of the proton on the sp3 carbon (leading to a substitution product). When a reaction proceeds this way, it is electrophilic aromatic substitution. There are a wide variety of electrophiles that can be introduced into a benzene ring in this way, and so electrophilic aromatic substitution is a very important method for the synthesis of substituted aromatic compounds. Ch17 Reactions of Aromatic Compounds (landscape).docx Page2 Bromination of Benzene Bromination follows the same general mechanism for the electrophilic aromatic substitution (EAS). Bromine itself is not electrophilic enough to react with benzene. But the addition of a strong Lewis acid (electron pair acceptor), such as FeBr3, catalyses the reaction, and leads to the substitution product.

  • Nitration of Toluene (Electrophilic Aromatic Substitution)
    Nitration of Toluene (Electrophilic Aromatic Substitution) Electrophilic aromatic substitution represents an important class of reactions in organic synthesis. In "aromatic nitration," aromatic organic compounds are nitrated via an electrophilic aromatic substitution mechanism involving the attack of the electron-rich benzene ring on the nitronium ion. The formation of a nitronium ion (the electrophile) from nitric acid and sulfuric acid is shown below. The sulfuric acid is regenerated and hence acts as a catalyst. It also absorbs water to drive the reaction forward. Figure 1: The mechanism for the formation of a nitronium ion. The methyl group of toluene makes it around 25 times more reactive than benzene in electrophilic aromatic substitution reactions. Toluene undergoes nitration to give ortho and para nitrotoluene isomers, but if heated it can give dinitrotoluene and ultimately the explosive trinitrotoluene (TNT). Figure 2: Reaction of nitric acid and sulfuric acid with toluene. Procedure: 1. Place a 5 mL conical vial, equipped with a spin vane, in a crystallizing dish filled with ice-water placed on a stirrer. 2. Pour 1.0 mL of concentrated nitric acid into the vial. While stirring, slowly add 1.0 mL of concentrated sulfuric acid. 3. After the addition of sulfuric acid is complete, add 1.0 mL of toluene dropwise and slowly over a period of 5 minutes (slow down if you see boiling. Reaction produces a lot of heat). 4. While Stirring, allow the contents of the flask to reach the room temperature. Stir at room temperature for another 5 minutes. 5. Add 10 mL of water into a small separatory funnel.

The mole ratio of sulphuric acid to nitric acid was varied from 0 to 4 and the extent of formation of ammonium dinitramide (ADN) was meas:red. The initial yield of ADN increases with increase of sulphuric acid content in the acid mixture and starts decreasing as the reaction time is increased. The variation of product yield with change in reaction time and total acid concentration was studied.

  • The Effects of Nitronium Ion on Nitration, Carbonylation and Coagulation of Human Fibrinogen
    Gen. Physiol. Biophys. (2008), 27, 55–58 55 Short Communication The effects of nitronium ion on nitration, carbonylation and coagulation of human fibrinogen M. B. Ponczek, P. Nowak and B. Wachowicz Department of General Biochemistry, University of Lodz, Poland Abstract. The effect of nitronium ion on nitration, carbonylation and coagulation of human fi- brinogen (Fg) in vitro was investigated. We observed that nitration of tyrosine, induced by NO2BF4 (0.01 mmol/l), was increased. No changes in carbonylation by NO2BF4 (0.01 mmol/l) were noticed. Mentioned alterations were associated with amplified coagulation of Fg. Higher concentrations of NO2BF4 (1 and 0.1 mmol/l) triggered growth of nitration and carbonylation of Fg, but led to inhibi- tion of polymerization. Slight nitration may be responsible for increase, whereas sizable nitration and oxidation may lead to inhibition of Fg coagulation. Key words: Fibrinogen — Nitrotyrosine — Carbonyl groups — Nitronium ion — Polymerization — Coagulation Fibrinogen (Fg) is the circulating precursor of fibrin, con- (Nowak and Wachowicz 2002). There is little known about verted by thrombin to fibrin monomers, which aggregate nitration of Fg by nitronium ion (NI).

Keywords: continuous flow; flow chemistry; nitration; nitric acid; microreactors; Guest Editor: A. Kirschning tubular reactor © 2014 Kulkarni; licensee Beilstein-Institut. License and terms: see end of document. Abstract This review highlights the state of the art in the field of continuous flow nitration with miniaturized devices. Although nitration has been one of the oldest and most important unit reactions, the advent of miniaturized devices has paved the way for new opportuni- ties to reconsider the conventional approach for exothermic and selectivity sensitive nitration reactions. Four different approaches to flow nitration with microreactors are presented herein and discussed in view of their advantages, limitations and applicability of the information towards scale-up. Selected recent patents that disclose scale-up methodologies for continuous flow nitration are also briefly reviewed. Review 1 Introduction Nitration of aromatics is one of the oldest and industrially most Based on estimations of 2007 and the proposed world produc- important reactions. A reaction between an organic compound tion capacity, the overall world production of nitric acid in 2012 and a nitrating agent leads to the introduction of a nitro group is assumed to be close to 78 Mi TPA, of which 85% is used for onto a carbon, nitrogen or oxygen atom of that organic com- the production of ammonium nitrate as fertilizer and 6% for pound [1].

Box 1346 Ann Arbor, Ml 48106-1346 Abstract This thesis consists of two main areas of study: the first being the mixed acid nitration of compounds in the series where X = NH, S, SO, and SO2, and the second area of study being the mechanism of rearrangement of N-nitrocarbazole. For each compound in the above series, the aim was to synthesise polynitro derivatives in a pure state, with high yields for use as energy rich constituents of pyrotechnic compositions. The tetranitro compounds hold the most interest for this particular application. The first compound studied was carbazole (X = NH). 1-Nitro-, 3-nitro-, 1,6- dinitro-, and 3,6-dinitrocarbazole were synthesised by literature methods. The synthesis of 1,3,6, 8-tetranitrocarbazole, first achieved over forty years ago, was improved by changing it from a one step to a two step reaction.

Page Intentionally Left Blank Page Intentionally Left Blank ABSTRACT Aromatic compounds such as toluene are commercially nitrated using a combination of nitric acid with other strong acids. This process relies on the use of highly corrosive chemicals and generates environmentally harmful waste, which is difficult to handle and dispose of. In this study aromatic nitration using solvent-free mechanochemical processing of environmentally benign precursors has been achieved and investigated. Mononitrotoluene (MNT) was synthesized by milling toluene with sodium nitrate and molybdenum trioxide as a catalyst. Several parameters affecting the desired product yield and selectivity were identified and varied. MNT yields in excess of 60% have been achieved in different tests. The desired product yield and selectivity were found to depend on the ratios of the reactants and the catalyst. A parametric study addressed the effects of milling time, temperature, milling media, and catalyst additives on the MNT yield and on the formation of various byproducts.

  • Nitric Acid - Wikipedia, the Free Encyclopedia
    Nitric acid - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Nitric_acid Nitric acid From Wikipedia, the free encyclopedia Nitric acid Nitric acid (HNO3), also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong acid. Colorless when pure, older samples tend to acquire a yellow cast due to the accumulation of oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as fuming nitric acid. Fuming nitric acid is characterized as white fuming nitric acid and red fuming nitric acid, depending on the amount of nitrogen dioxide present. At concentrations above 95% at room temperature, it tends to develop a yellow color due to decomposition. An alternative IUPAC name is oxoazinic acid.
