Isocyanide-Induced Esterification of Sulfinic Acids to Access Sulfinates

The isocyanide-induced esterification of sulfinic acids with alcohols or thiophenols access to sulfinates has been developed. Various primary, secondary, and tertiary alcohols could be compatible with the established protocols. Notably, such an isocyanide-induced synthetic strategy presented the advantages of simple operation, good functional group tolerance, and more than 40 examples up to 99% yields. (Figure presented.).

Efficient electrosynthesis of sulfinic esters via oxidative cross-coupling between alcohols and thiophenols

A new protocol for S O bond formation was developed by electrochemical oxidative cross-coupling between alcohols and thiophenols. With this strategy, a series of valuable sulfinic ester derivatives were synthesized up to 96% yield from basic starting materials. A preliminary mechanistic investigation reveals that this reaction involves oxygen reduction reaction (ORR).

A sustainable oxidative esterification of thiols with alcohols by a cobalt nanocatalyst supported on doped carbon

Here, we developed a new cobalt nanocatalyst supported on N-SiO2-doped activated carbon (Co/N-SiO2-AC), which exhibits excellent catalytic performance towards the oxidative esterification of (hetero)aryl and alkyl thiols with alcohols. A wide array of sulfinic esters were efficiently afforded in an exclusive chemoselective manner. The developed synthetic method proceeds with the merits of mild reaction conditions, broad substrate scope, operational simplicity, good functional group tolerance, earth-abundant and reusable cobalt catalysts, the utilization of renewable alcohols as the coupling partners and molecular O2 as the sole oxidant, which offers a practical method for sustainable synthesis of sulfinic esters.
