title: C-C Coupling of Benzyl Fluorides Catalyzed by an Electrophilic Phosphonium Cation.
abstract: The activation and cleavage of benzyl fluorides by the electrophilic organofluorophosphonium catalyst, [(C6 F5 )3 PF][B(C6 F5 )4 ], is reported and used for the preparation of 1,1-diarylalkanes (37 examples) and substituted aryl homoallylic alkenes (14 examples). This procedure involves mild conditions, avoids harmful waste, and is compatible with a range of substituted arenes and allylic silanes.
