To explore sodium thiosulfate’s potential as a sulfur transfer agent for thiosulfonylation reactions.
Utilized sodium thiosulfate in reactions with alkynes.
Evaluated the formation of bis-(Z)-vinyl sulfones.
Assessed the reaction conditions for optimal stereoselectivity.
Sodium thiosulfate successfully acted as a sulfur donor in the reaction.
Bis-(Z)-vinyl sulfones were synthesized with high stereoselectivity.
The procedure demonstrated low environmental impact due to the green nature of the reactants.

Implication

Novel reactivity of sodium thiosulfate provides an eco-friendly sulfur source for vinyl sulfone synthesis in organic chemistry.

Abstract

Here, we describe a novel and untapped reactivity profile of sodium thiosulfate, where it acts as an odourless, inexpensive and green sulfur surrogate equivalent to hydrogen sulfide (H2S) for in...
