Nickel-Catalyzed Gas-Free Reductive Carbonylation of Aryl Thianthrenium Salts to Access Aryl Amides and Aryl Thioesters

Organic Letters, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

A nickel-catalyzed site-selective reductive carbonylation of arenes via aryl thianthrenium salts is described. Using Mo(CO)6 as a convenient solid CO source and reductant employing nitroarenes sulfonyl chlorides readily available nitrogen sulfur sources, range amides thioesters were successfully synthesized in moderate to good yields. The utility this transformation demonstrated through the synthesis antimicrobial agents late-stage functionalization biorelevant molecules.
