Highly regio- and diastereoselective Cu-catalyzed hydroborylation and hydrosilylation of difluorocyclopropenes with B2pin2 and PhMe2Si–Bpin†
Abstract
An efficient synthetic method for preparing trans-difluorocyclopropyl boronates and trans-difluorocyclopropyl silanes was easily achieved through a copper-catalyzed hydroborylation and hydrosilylation of difluorocyclopropenes with bis(pinacolato)diboron and silylboronate, respectively.
