    125 Exercise 15 - Preparation of a Key for Reaction-Map of Organic Chemistry (see Appendix C in student manual) Abstract: The Reaction -Map of Organic Chemistry has been designed to give organic chemistry students an overview of most of the reactions needed for the organic chemistry course. The chart has been partially organized according to the periodic table on the horizontal axis and according to carbon oxidation level on the vertical axis. In addition the carboxyls are grouped vertically according to decreasing reactivity and carbon - carbon bond forming reactions are emphasized with bold arrows. The chart provides a study aide for students and should help students develop synthetic routes from one functional group to another. The chart should be especially useful for students studying for the final examination for the two semester organic chemistry course. In addition to the chart, three keys are available that organize the reactions according to mechanism, functional group preparations and functional group reactions. Chemistry can be thought of a search for order in matter and this chart attempts to provide some insight into the order that exists in organic chemistry. Please note, “Supporting information reprinted with permission from J. Chem. Ed. 2007, 84(7), 1224. Copyright 2007 American Chemical Society.” Reaction-Map as a Study Aid At the end of a two semester course in organic chemistry, a student should be able to perform the exercises below. (Note: In addition to the exercises below, a student of organic chemistry should be able to demonstrate competency with spectroscopic, stereochemical and multistep synthetic challenges.) By performing the exercises below should result in the preparation of three keys for the Reaction-Map of Organic Chemistry.

The polymerization proceeded in solution using halide exchange technique to control ATRP. Fourier transform infrared spectroscopy (FT-IR) and 1H NMR studies confirm the composition of PEO–Br macroinitiator and related diblock co- polymers. The results obtained by GPC analysis show that the number average molecular weight was increased versus monomer conversion and the polydispersities were quite low (<1:10), which is the character of a controlled/‘‘living’’ polymerization. Moreover, the crystallization behavior of PEO-b-PMMA block copolymers was studied by means of differential scanning calorimetry (DSC). It was found

Conversion of a carboxylic acid to an acyl chloride provides access to any of the other derivatives because the acyl chloride is at the top of the reactivity scale. But how can the acyl chloride be prepared from the acid when the acid is lower on the re- activity scale? This can be accomplished by using an even more reactive compound to drive the equilibrium in the desired direction. The reagent that is employed in the vast majority of cases is thionyl chloride, SOCl2.

  • Recent Advances in Acyl Suzuki Cross-Coupling
    catalysts Review Recent Advances in Acyl Suzuki Cross-Coupling Jonathan Buchspies and Michal Szostak * Department of Chemistry, Rutgers University, 73 Warren Street, Newark, NJ 07102, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-973-353-5329 Received: 17 December 2018; Accepted: 28 December 2018; Published: 8 January 2019 Abstract: Acyl Suzuki cross-coupling involves the coupling of an organoboron reagent with an acyl electrophile (acyl halide, anhydride, ester, amide). This review provides a timely overview of the very important advances that have recently taken place in the acylative Suzuki cross-coupling. Particular emphasis is directed toward the type of acyl electrophiles, catalyst systems and new cross-coupling partners. This review will be of value to synthetic chemists involved in this rapidly developing field of Suzuki cross-coupling as well as those interested in using acylative Suzuki cross-coupling for the synthesis of ketones as a catalytic alternative to stoichiometric nucleophilic additions or Friedel-Crafts reactions. Keywords: Suzuki cross-coupling; acyl cross-coupling; acylation; ketones; acylative cross-coupling; palladium; nickel; phosphine; N-heterocyclic carbene; Suzuki-Miyaura 1. Introduction The Suzuki cross-coupling represents the most powerful C–C bond forming reaction in organic synthesis [1]. Traditional Suzuki cross-coupling (also referred to as Suzuki–Miyaura cross-coupling) involves the coupling of an organoboron reagent with an aryl halide (pseudohalide) and is most commonly employed for the synthesis of biaryls by a C(sp2)–C(sp2) disconnection using a palladium or nickel catalyst (Figure1A) [ 2,3]. Since the initial report in 1979, many variants of the Suzuki cross-coupling have been discovered [4].

  • Hydrides As Reducing Agents
    Hydrides as Reducing Agents Lithium aluminum hydride (LiAlH4) is a strong reducing agent. It will donate hydride (“H-”) to any C=O containing functional group. Examples: + 2. H3O 1. LiAlH4 (or just H2O) aldehyde primary alcohol 1. LiAlH4 2. H2O ketone secondary alcohol Hydrides as Reducing Agents Lithium aluminum hydride (LiAlH4) is a strong reducing agent. It will reduce almost any C=O containing functional group to an alcohol. Example: 1. LiAlH4 2. H2O ester One and then another equivalent equivalent adds, of H- adds, unavoidably. Reduced by LiAlH4 to an alcohol: aldehyde ketone carboxylic acid ester acyl halide Double Addition of Hydride to Carboxylic Acids and Derivatives Why? Ketones and aldehydes are more electrophilic than acids, esters and acyl halides. As soon as a ketone or aldehyde is Lone pair donation by generated, it is immediately reduced oxygen reduces partial again. positive charge on C=O carbon. Reduced by LiAlH4 to an alcohol: aldehyde ketone carboxylic acid ester acyl halide Hydrides as Reducing Agents Exception: LiAlH4 reduces amides to amines. Examples: 1. LiAlH4 Mechanism depends slightly on whether amide has an N-H or 2. H2O not. But the result is the same. 1. LiAlH4 2. H2O Reduced by LiAlH4 to an alcohol: aldehyde ketone carboxylic acid ester acyl halide Hydrides as Reducing Agents Sodium borohydride (NaBH4) is a mild reducing agent. It is only capable of reducing aldehydes and ketones. NaBH4 NaBH4 isn’t as basic as LiAlH4, EtOH so reaction can be conducted in protic solvent, and separate workup step isn’t essential. aldehyde primary alcohol NaBH4 EtOH Reduced by NaBH4: ketone secondary alcohol aldehyde ketone Biological Cofactors as Redox Agents LiAlH4 isn’t used in biology, but biological reductants are mechanistically similar.

  • Alcohols and Ethers
    ALCOHOLS AND ETHERS The hydroxyl group is one of the most important functional groups of na- turally occurring organic molecules. All carbohydrates and their derivatives, including nucleic acids, have hydroxyl groups. Some amino acids, most ste- roids, many terpenes, and plant pigments have hydroxyl groups. These sub- stances serve many diverse purposes for the support and maintenance of life. One extreme example is the potent toxin tetrodotoxin, which is isolated from puffer fish and has obvious use for defense against predators. This compound has special biochemical interest, having six different hydroxylic functions arranged on a cagelike structure: tetrodotoxin On the more practical side, vast quantities of simple alcohols - metha- nol, ethanol, 2-propanol, 1-butan01 - and many ethers are made from petro- leum-derived hydrocarbons. These alcohols are widely used as solvents and as intermediates for the synthesis of more complex substances. 15 Alcohols and Ethers The reactions involving the hydrogens of alcoholic OH groups are expected to be similar to those of water, HOH, the simplest hydroxylic com- pound. Alcohols, ROH, can be regarded in this respect as substitution products of water. However, with alcohols we shall be interested not only in reactions that proceed at the 8-H bond but also with processes that result in cleavage of the C-0 bond, or changes in the organic group R. The simple ethers, ROR, do not have 0-H bonds, and most of their reactions are limited to the substituent groups. The chemistry of ethers, there- fore, is less varied than that of alcohols. This fact is turned to advantage in the widespread use of ethers as solvents for a variety of organic reactions, as we already have seen for Grignard reagents (Section 14- 10).
