Facile Access to Difluoromethylene-Linked Strained Aliphatic Rings from 2-(Difluoromethylene)cyclobutyl Sulfonium Salts (CB-DFAS) and [1.1.1]Propellane

A chemodivergent platform that delivers three unprecedented, difluoromethylene (CF2)-bridged strained scaffolds from 2-(difluoromethylene)cyclobutyl sulfonium salts (CB-DFASs) and [1.1.1]propellane (TCP) has been developed. Simply by modulating reaction conditions, the combination of...
