The green chemistry paradigm in modern organic synthesis

Russian Chemical Reviews, Journal Year: 2023, Volume and Issue: 92(12), P. RCR5104 - RCR5104

Published: Dec. 1, 2023

After the appearance of green chemistry concept, which was introduced in vocabulary early 1990s, its main statements have been continuously developed and modified. Currently, there are 10–12 cornerstones that should form basis for an ideal chemical process. This review analyzes accumulated experience achievements towards design products processes reduce or eliminate use generation hazardous substances. The presents views leading Russian scientists specializing various fields this subject, including homogeneous heterogeneous catalysis, fine basic organic synthesis, electrochemistry, polymer chemistry, based on bio-renewable feedstocks energetic compounds materials. A new approach to quantitative evaluation environmental friendliness by authors is described. <br> bibliography includes 1761.

The Reaction of Aryl Thiols or Thioureas with o‐Diiodoarenes/NaH to Access o‐Iodoaryl Thioethers

Advanced Synthesis & Catalysis, Journal Year: 2024, Volume and Issue: 366(7), P. 1538 - 1544

Published: Feb. 8, 2024

Abstract Herein we report a method for the synthesis of thioethers by forging C(aryl)‐S bond via an aryne mechanism. The active species can be generated from o ‐diiodoarenes and NaH in THF at room temperature, then lead to arylations wide range aryl thiols thioureas. Different transition metal‐catalyzed cross‐coupling reactions, no disubstituted byproduct is formed our protocol. ‐iodoaryl thioether products are intermediates that could transformed into pharmaceutically interesting molecules.

Copper‐Mediated C−H Chalcogenation of Heterocycles: Application to the Synthesis of Chalcogenoxanthones

Advanced Synthesis & Catalysis, Journal Year: 2023, Volume and Issue: 365(19), P. 3353 - 3359

Published: Aug. 16, 2023

Abstract A copper‐mediated C( sp 2 )−H chalcogenation of heterocycles with readily available dichalcogenide, benzeneselenol and thiol is described. This protocol demonstrates scalability, good chemo‐ regio‐selectivity, as well broad functional group tolerance, which overall provides an accessible method to valuable aryl chalcogenides. The chalcogenated picolinamide products could be further transformed into selenoxanthones thioxanthone scaffolds through intramolecular cyclization via a semi‐one pot process.
