NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).

Metal- And oxidant-free electrochemical synthesis of sulfinic esters from thiols and alcohols

An efficient and eco-friendly electrochemical synthesis of various sulfinic esters from thiols and alcohols via sequential S-H/S bond cleavage and double S-O bond formation under mild reaction conditions has been developed. Stoichiometric oxidants, metal catalysts, activating agents and even added bases were avoided in this method, and the only by-product generated from this reaction was dihydrogen gas which could serve as a green source of energy. Various functional groups are compatible with this green protocol which can be easily conducted on a gram-scale.

Tert-Butyl Sulfoxide as a Starting Point for the Synthesis of Sulfinyl Containing Compounds

Sulfoxides bearing a tert-butyl group can be activated using N-bromosuccinimide (NBS) under acidic conditions and then subsequently treated with a variety of nitrogen, carbon, or oxygen nucleophiles to afford a wide range of the corresponding sulfinic acid amides, new sulfoxides, and sulfinic acid esters.
