Under typical copper-catalyzed hydroboration conditions, β-(trifluoromethyl)styrenes demonstrate unusal reactivities by forming difluoromethylated alkenes via a net protodefluorination process. This is also distinct from trifluoromethyl alkenes with alkyl substituents where defluoroborylation products predominate.
在典型的铜催化硼氢化条件下, β- (三氟甲基)苯乙烯通过净原脱氟过程形成二氟甲基化烯烃,从而表现出不寻常的反应活性。这也不同于以脱氟硼化产物为主的具有烷基取代基的三氟甲基烯烃。
