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.).

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.
Alkyl sulfinates: Formal nucleophiles for synthesizing TosMIC analogs

Alkyl sulfinates function as formal nucleophiles in Mannich-type reactions to give sulfonyl formamides, which are readily dehydrated to the corresponding sulfonylmethyl isonitriles. The efficient, two-step synthesis provides a general route to sulfonylmethyl isonitriles from readily available methyl sulfinates or thiols. Mechanistic analysis reveals that the unusual nucleophlicity of the alkyl sulfinates arises from the in situ release of sulfinic acids.
