Synthesis and applications of sodium sulfinates (RSONa): a powerful building block for the synthesis of organosulfur compounds.

This review highlights the preparation of sodium sulfinates (RSONa) and their multifaceted synthetic applications. Substantial progress has been made over the last decade in the utilization of sodium sulfinates emerging as sulfonylating, sulfenylating or sulfinylating reagents, depending on reaction conditions. Sodium sulfinates act as versatile building blocks for preparing many valuable organosulfur compounds through S-S, N-S, and C-S bond-forming reactions.

A straightforward and convenient synthesis of functionalized allyl thiosulfonates and allyl disulfanes.

A practical, highly flexible and eco-friendly method has been developed for the synthesis of allyl thiosulfonates using Morita-Baylis-Hillman (MBH) allyl bromides and sodium arylthiosulfonates, which were readily assembled without any reagent/catalyst. Moreover, the allyl thiosulfonates were successfully transformed into a set of two synthetically viable diallyl disulfanes and unsymmetrical allyl disulfanes in the presence of CsCO. The present protocols are operationally simple and convenient to generate a wide range of functionalized allyl thiosulfonates and allyl disulfanes in good to excellent yields.
