A visible-light-triggered radical cascade sulfonylation/aryl migration/desulfonylation and C–S/Se bond formation reaction of butenyl benzothiazole sulfone with thiosulfonates or selenosulfonates is developed. This study affords the 1,2,4-trifunctionalization of butenyl benzothiazole sulfone derivatives under mild conditions.

Bicyclo[1.1.1]pentane is widely recognized as the bioisostere for aryl, tert-butyl, and internal alkynes. Herein we report an efficient and practical method for the preparation of selenoether and thioether functionalized bicyclo[1.1.1]pentanes from selenosulfonates/thiosulfonates and propellane. A variety of valuable bicyclo[1.1.1]pentanes bearing both selenoether/thioether and sulfone are obtained

A Cu-catalyzed cascade reaction of four-membered silacyclobutanes (SCBs) and thiosulfonates to construct S (Se)-containing organosiliconcompounds was developed. The protocol shows a wide range of substrate scope, high functional group compatibility and mild reaction conditions. New C–S (Se) and Si–O bonds were constructed in one step.

A visible-light promoted radical reaction between α-bromoacetophenone and thiosulfate has been reported. Two C−S bonds or one C−S and one C−Se bond can be stably constructed and the thiosulfonate is fully utilised with good atomic economy. The reaction uses ethanol as a green solvent, with mild reaction conditions and good substrate universality.
