Download or read book S Heterocycles written by Shrikaant Kulkarni and published by Royal Society of Chemistry. This book was released on 2024-07-24 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterocyclic compounds are vital in synthetic chemistry, pharmaceuticals, agrochemicals, and materials science. The concept of S-heterocyclic compounds revolves around organic compounds that contain heterocyclic rings, and sulfur (S) is one of the heteroatoms within the ring structure. S-enabled heterocycles have emerged as one of the key classes of heterocycles and have attracted tremendous attention attributed to their identity as ‘privileged pharmacological structures’ across natural products and highly active pharmaceutical agents. This edited volume reports the latest developments in practical and selective reactions and methods and provides details of the structural diversity of heterocycles. Together, the chapters provide a comprehensive view of the diversity of methods, properties, and the variety of applications in the construction of S-heterocycles. Divided into four parts, the book covers in part one the chemistry, synthesis pathways, property profile, and applications of thiazoles, and includes five chapters. Part two details thiadiazoles and part three thiopyrans, thiazine, and thiazepine. Lastly, part four focuses on thiophenes. This volume will be of immense help to academicians, researchers, and students pursuing research and looking at the future of heterocyclic chemistry.

Download or read book Bitumens and Bitumen Emissions and Some N and S heterocyclic Polycyclic Aromatic Hydrocarbons written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2013 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of bitumens and their emissions, the N-heterocyclic polycyclic aromatic hydrocarbons benz[a]acridine, benz[c]acridine, dibenz[a,h]acridine, dibenz[a,j]acridine, dibenz[c,h]acridine, carbazole and 7H-dibenzo[c,g]carbazole, as well as the S-hetrocyclic polycyclic aromatic hydrocarbons benzo[b]naphtho[2,1-d]thiophene and dibenzothiophene. Bitumens are produced by distillation of crude oil during petroleum refining, and also occur naturally. Bitumens can be divided into six broad classes, according to their physical properties and specifications required for different applications. The major use (about 80%) of bitumens is for road paving; other uses include roofing, waterproofing, sealing and painting. The term "bitumen" should not be confused with "asphalt", which refers to the mixture of bitumen (4-10% by weight), small stones, sand and filler used for road paving. Bitumens are complex mixtures that contain a large number of organic chemical compounds. Application of bitumens may generate emissions (fumes and vapours) that may contain, among volatile and non-volatile compounds, a number of known or probable carcinogens. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of various occupations that entail exposure to bitumens and bitumen emissions, including road paving, roofing, and application of mastic asphalt, and to various heterocyclic polycyclic aromatic compounds.
