A practical synthetic approach to the difluoro-substituted bicyclo[1.1.1]pentanes was developed. The key step was an addition of difluorocarbene (:CF2) to electron-rich bicyclo[1.1.0]butanes by the CF3TMS/NaI system. The obtained difluoro-bicyclo[1.1.1]pentanes are suggested to be used as saturated bioisosteres of benzene rings for the purpose of drug discovery projects.

Described herein is our effort toward achieving the decarboxylative functionalization of 2,2-difluorobicyclo[1.1.1]pentane (BCP-F2) building blocks. When compared with the nonfluorinated bicyclo[1.1.1]pentane (BCP) analogues, we discovered divergent reactivities. This is the first successful decarboxylative coupling of BCP-F2 building blocks reported via the photoredox mechanism.
