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 under mild conditions with good yields. The protocol features broad functional group compatibility, excellent atom-economy, simple operation, and gram-scale preparation.
