Kammer, Director Polycyclic Aromatic Hydrocarbon Structure Index Lane C. Sander and Stephen A. Wise Chemical Science and Technology Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 This tabulation is presented as an aid in the identification of the chemical structures of polycyclic aromatic hydrocarbons (PAHs). The Structure Index consists of two parts: (1) a cross index of named PAHs listed in alphabetical order, and (2) chemical structures including ring numbering, name(s), Chemical Abstract Service (CAS) Registry numbers, chemical formulas, molecular weights, and length-to-breadth ratios (L/B) and shape descriptors of PAHs listed in order of increasing molecular weight. Where possible, synonyms (including those employing alternate and/or obsolete naming conventions) have been included. Synonyms used in the Structure Index were compiled from a variety of sources including “Polynuclear Aromatic Hydrocarbons Nomenclature Guide,” by Loening, et al. [1], “Analytical Chemistry of Polycyclic Aromatic Compounds,” by Lee et al. [2], “Calculated Molecular Properties of Polycyclic Aromatic Hydrocarbons,” by Hites and Simonsick [3], “Handbook of Polycyclic Hydrocarbons,” by J. R. Dias [4], “The Ring Index,” by Patterson and Capell [5], “CAS 12th Collective Index,” [6] and “Aldrich Structure Index” [7].

Because it is one of the smallest two-dimensional N-containing polyheterocyclic aromatic systems, it has been used as the basic scaffold for larger 2D N-substituted polyheterocyclic aromatics. 10 Furthermore, it is the building block of choice in a plethora of molecular, macromolecular and supramolecular systems for a variety of applications. This review is aimed to critically review the research performed during the almost three decades of research based on HAT from the synthetic, theoretical and applications point of view. -

In nomenclature, fusion is the operation that creates a common bond between two rings, each ring contributing one bond and the two atoms directly attached to the bond. This type of fusion is called ortho- or ortho- and peri-fusion if two adjacent bonds are involved. The term fusion is also used todesc ribe the operation creating a common atom between two ring systems, each contributing one atom. This type of fusion is called spirofusion (see P-24.1). Traditionally, ortho- and ortho- and peri-fusion were simply called fusion and the resulting polycyclic systems were referred to as fused ring systems or fused ring compounds. The term 'spirofusion' is new in nomenclature, and to avoid ambiguity 'fusion' should not be used without the prefix 'spiro' when 'spirofusion' is intended."

Transformation of Phenanthrene by Mycobacterium Sp. ELW1 and the Formation of Toxic Metabolites
AN ABSTRACT OF THE THESIS OF Jill E. Schrlau for the degree of Master of Science in Environmental Engineering presented on September 20, 2016. Title: Transformation of Phenanthrene by Mycobacterium sp. ELW1 and the Formation of Toxic Metabolites. Abstract approved: _____________________________________________________________________ Lewis Semprini Staci Simonich The ability of Mycobacterium sp. ELW1, a novel microbe capable of alkene oxidation, to co-metabolize phenanthrene (PHE) was studied. ELW1 was able to completely co-metabolize PHE, at different concentrations below its water solubility limit, in an aqueous environment. The alkene monooxygenases in ELW1, used to initiate oxidation of PHE, were effectively inhibited by 1-octyne despite some PHE transformation observed. PHE metabolites consisted of only hydroxyphenanthrenes (OHPHEs) with trans-9,10-dihydroxy-9,10-dihydrophenanthrene (trans-9,10-PHE), the primary product, comprising more than 90% of the total metabolites formed in both PHE-exposed cells and 1-octyne controls. Mass balance was estimated by summing the zero-order formation rates of OHPHE metabolites and comparing these to the zero-order transformation rates PHE in PHE-exposed cells. The transformation rates of PHE and were in good agreement with the formation rates of the metabolites. PHE transformation followed first-order rates that, when normalized by biomass, were in the range of those estimated by the ratio of the Michaelis-Menten kinetic variables of maximum transformation rate (kmax) to the half-saturation constant (KS). Estimated values for kmax to KS obtained through both non-linear and linearization methods resulted in kmax/KS estimates that were a factor of ~3 lower compared to experimental values. -

Cycloadditions for Rapid, Scalable Access to Alkynylated Polycyclic Aromatic Cite This: Chem
Chemical Science EDGE ARTICLE View Article Online View Journal | View Issue Site-selective [2 + 2 + n] cycloadditions for rapid, scalable access to alkynylated polycyclic aromatic Cite this: Chem. Sci., 2020, 11,3028 hydrocarbons† All publication charges for this article have been paid for by the Royal Society of Chemistry Gavin R. Kiel, Harrison M. Bergman and T. Don Tilley * Polycyclic aromatic hydrocarbons (PAHs) are attractive synthetic building blocks for more complex conjugated nanocarbons, but their use for this purpose requires appreciable quantities of a PAH with reactive functional groups. Despite tremendous recent advances, most synthetic methods cannot satisfy these demands. Here we present a general and scalable [2 + 2 + n](n ¼ 1 or 2) cycloaddition strategy to access PAHs that are decorated with synthetically versatile alkynyl groups and its application to seven structurally diverse PAH ring systems (thirteen new alkynylated PAHs in total). The critical discovery is the site-selectivity of an Ir-catalyzed [2 + 2 + 2] cycloaddition, which preferentially cyclizes tethered diyne units with preservation of other (peripheral) alkynyl groups. The potential for generalization of the site- Creative Commons Attribution-NonCommercial 3.0 Unported Licence. selectivity to other [2 + 2 + n] reactions is demonstrated by identification of a Cp2Zr-mediated [2 + 2 + 1]/metallacycle transfer sequence for synthesis of an alkynylated, selenophene-annulated PAH. The new PAHs are excellent synthons for macrocyclic conjugated nanocarbons. As a proof of concept, four were subjected to alkyne metathesis catalysis to afford large, PAH-containing arylene ethylene macrocycles, which possess a range of cavity sizes reaching well into the nanometer regime. Notably, these high- Received 2nd December 2019 yielding macrocyclizations establish that synthetically convenient pentynyl groups can be effective for Accepted 15th February 2020 metathesis since the 4-octyne byproduct is sequestered by 5 A˚ MS.
