Abstract
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 to give [Rh{Si(OEt)3}(CF3CHCF2)(PEt3)2] (5). Two equivalents of complex 2 reacted further by C−F bond oxidative addition to yield [Rh(CF=CHCF3)(PEt3)2(μ‐F)3Rh(CF3CHCF2)(PEt3)] (9). The role of the fluorido ligand on the reactivity of complex 2 was assessed by comparison with the analogous chlorido complex. The use of complexes 1, 4 and 6 as catalysts for the derivatization of 1,1,3,3,3‐pentafluoropropene provided products, which were generated by hydrodefluorination, hydrometallation and germylation reactions.
