A series of new (E)-pentafluoropropenyl complexes of Hg, Ge, Sn, and Pb are reported derived from CFH=CFCF3 ((Z)-HFC-1225ye). Unequivocal assignment of the geometry of the products was achieved via a multinuclear (1H, 13C, 19F, 119Sn, and 199Hg) NMR study. These conclusions are confirmed in the single-crystal X-ray structures of Ph3Ge(CF=CFCF3) and Ph3Sn(CF=CFCF3). In the solid-state structures of both molecules, short contacts are observed between one of the fluorine atoms of the CF3 group and the metal center. The Bu3Sn(CF=CFCF 3) compound acts as an effective source of the pentafluoropropenyl group in a series of palladium-catalyzed Stille-Liebeskind reactions to generate new aryl-pentafluoropropenyl systems.
