The reaction of the rhodium(I) complexes [Rh(E)(PEt3)3] (E=GePh3 (1), H (6), F (7)) with 1,1,3,3,3-pentafluoropropene afforded the defluorinative germylation products Z/E-2-(triphenylgermyl)-1,3,3,3-tetrafluoropropene and the fluorido complex [Rh(F)(CF3CHCF2)(PEt3)2] (2) together with the fluorophosphorane E-(CF3)CH=CF(PFEt3). For [Rh(Si(OEt)3)(PEt3)3] (4) the coordination of the fluoroolefin was found
