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.

Arenecarbaldehydes ArCHO were allowed to react with a carbenoid reagent CF3CX2Mtl (X=Cl, Mtl=ZnCl, X=F, Mtl=LI) to give the adducts ArCH(OH)CX2CF3 whose hydroxyl group was substituted by fluorine.Dehydrohalogenating of the resultant ArCHFCX2CF3 (X=Cl or F
An Improved Synthesis of 1-Phenylpentafluoropropenes
Dmowski, Wojciech
, p. 25 - 30 (2007/10/02)
1-Phenylpentafluoropropene and a number of its para- and ortho-substituted derivatives were prepared in high yields by reaction of hexafluoropropene with etheral solutions of corresponding phenylmagnesium bromides in sealed glass tubes under autogenous pressure.The products were obtained as mixtures of the Z and E isomers, which ratios varied from 1/2 to 1/6 in favour of the E forms. 19F n.m.r. and i.r. spectra and b.p. of the 1-phenylpentafluoropropenes are reported.
