Direct C−H Sulfuration: Synthesis of Disulfides, Dithiocarbamates, Xanthates, Thiocarbamates and Thiocarbonates

Chemistry - An Asian Journal, Год журнала: 2024, Номер 19(9)

Опубликована: Фев. 29, 2024

Abstract In light of the important biological activities and widespread applications organic disulfides, dithiocarbamates, xanthates, thiocarbamates thiocarbonates, continual persuit efficient methods for their synthesis remains crucial. Traditionally, preparation such compounds heavily relied on intricate multi‐step syntheses use highly prefunctionalized starting materials. Over past two decades, direct sulfuration C−H bonds has evolved into a straightforward, atom‐ step‐economical method organosulfur compounds. This review aims to provide an up‐to‐date discussion disulfuration, dithiocarbamation, xanthylation, thiocarbamation thiocarbonation, with special focus describing scopes mechanistic aspects. Moreover, synthetic limitations some these methodologies, along key unsolved challenges be addressed in future are also discussed. The majority examples covered this accomplished via metal‐free, photochemical or electrochemical approaches, which alignment overraching objectives green sustainable chemistry. comprehensive consolidate recent advancements, providing valuable insights dynamic landscape strategies crucial classes

Bis(dialkylaminethiocarbonyl)disulfides Act as Electron Acceptors for EDA Complexes for the Synthesis of Dithiocarbamate Derivatives under Visible Light

The Journal of Organic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 14, 2025

This study proposes a green and efficient atom- step-economical method for converting hazardous CS2 to dithiocarbamate derivatives under visible light irradiation catalyst-free conditions. By the construction of novel C-S C-N bonds, series β-dicarbonyl compounds amines are incorporated into products. Under light, amine first form bis(dialkylaminethiocarbonyl)disulfides, which then react with K2CO3-activated electron donor-acceptor (EDA) complexes subsequently generate target confirms time that bis(dialkylaminethiocarbonyl)disulfides can act as acceptors an EDA complex compounds, coupled product light.
