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.

In this report, we describe the multicomponent coupling reaction between arynes, (pseudo)halides, and an electrophilic chalcogen species. Addition of a copper salt enabled smooth conversion by suppressing side reactions. A variety of different aryne precursors as well as seleno- and thiosulfonates were employed, yielding a broad spectrum of ortho-(pseudo)halogenated chalcogenides. This motif was subjected

Unsymmetric sulfides and selenides have great applications in the pharmaceutical field. Herein, we describe the reductive coupling reaction of xanthate esters with sulfur-containing and selenium-containing compounds (thio(seleno)sulfonates and disulfides(selenides)) under the nickel-catalyzed condition. It provides a mild and effective method for the synthesis of unsymmetric sulfides and selenides
