Electrochemical synthesis of sulfinic esters from alcohols and thiophenols
He, Yang,Zhang, Jinli,Xu, Liang,Wei, Yu
, (2020)
Electrochemical oxidative couplings between S[sbnd]H and O[sbnd]H bonds are achieved herein directly from readily-available alcohols and thiophenols, affording a series of diverse sulfinic esters. This strategy can take advantage of 6 equivalents of alcohol, relative to thiophenol, to achieve moderate to good yields, without the assistance of any metallic catalysts, bases, and additional oxidants.

Reaction of alcohols with sodium arenesulfinates could afford either sulfones or sulfinates, and O-attack of sulfinate anions onto the in situ generated carbocation intermediates from alcohols was the previous proposed reaction mechanism in many syntheses of sulfinates. This concept, which is often used consciously or unconsciously, was revised herein by using isotopic labeling experiments and development of an improved sulfinate synthesis. The improved sulfinate synthetic protocol possesses many advantages such as a high sulfinate/sulfone selectivity, a broad substrate scope, metal-free, and mild reaction conditions. The revised reaction mechanism necessitates revision of many previous proposed reaction mechanisms in literatures.
