Abstract

XeF2 reacts with [M(CO)X(PEt(3))(2)], 1 (M = Rh, Ir; X = Cl, Br, I) to give the cis-addition product, [M(CO)F(2)X(PEt(3))(2)], characterised by NMR spectroscopy; cis- and trans-[Ir(DPPE)(2)F-2](+) have been obtained and characterised similarly. With complexes of 6-coordinated Ir(III), reaction below 300K only occurs where, formally, F-2 can be added to a ligand (such as PF2 or PHZ). [Ir(CO)(3)(PEt(3))2](+) and related species react with XeF2 to form novel fluoroacyl complexes of Ir(III), eg [Ir(CO)(2)(COF)F(PEt(3))(2)](+), 9; reactions of 9 with silyl compounds and with Lewis acids are discussed. Complexes 1 react with SF4 to form [M(CO)FX(PEt(3))(2)(SF3)]; two distinct nuxional processes have been observed in the SF3-groups. Analogous SeF3 derivatives are formed from 1 and SeF4; with TeF4, the rhodium complexes form [Rh(CO)X(PEt(3))2(TeF3)](+)[TeF5](-).
