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.).

Dual Roles of Rongalite: Reductive Coupling Reaction to Construct Thiosulfonates Using Sulfonyl Hydrazides

A tunable and practical transformation of structurally diverse sulfonyl hydrazides into thiosulfonates in the presence of Rongalite (NaHSO 2·CH 2O) was developed. Transition-metal-free conditions, operational simplicity, and readily available reagents are the striking features of this protocol. It is the first example for the synthesis of thiosulfonates using sulfonyl hydrazides with the assistance of reductant. Additionally, the mechanistic studies revealed that this transformation probably undergoes via a reducing-coupling pathway.
