A novel approach for the direct conversion of alkylsulfonyl derivatives into alkylcarbonyl derivatives via tin-free radical carbonylation

Palladium-Catalyzed Reductive Desulfonative Aminocarbonylation of Benzylsulfonyl Chlorides with Nitroarenes to Phenylacetamides

Herein, we demonstrate a new procedure for the direct using benzylsulfonyl chlorides as versatile C(sp3) electrophiles in a palladium-catalyzed reductive desulfonative aminocarbonylation reaction. Using nitroarenes as readily accessible and stable...

Tin-free radical carbonylation of alkylsulfonyl derivatives into alkylcarbonyl derivatives

A simple radical approach based on tin-free radical carbonylation is devised for the direct conversion of alkylthiosulfonates, alkylsulfonyl cyanides, and alkylsulfonyl oxime ethers into the corresponding alkyl thiol esters, acyl cyanides, and acylated oxime ethers in a single step. The present approach is very simple, highly efficient, and minimizes the formation of byproducts.
