The oxidative addition of iodomethane to trans-halogenocarbonylbis(triarylphosphine)rhodium(I) and the subsequent isomerisation via methyl transfer to an acetyl complex
Abstract
A study has been made of the effects of the ligands, halide, X–, and tertiary phosphine, R3P, on the oxidative addition of iodomethane to trans-halogenocarbonylbis(tertiaryphosphine)rhodium(I), trans-RhX(CO)(PR3)2 to give, initially, RhXIMe(CO)(PR3)2 and finally, the acetyl complex RhXI(COMe)(PR3)2. Approximate kinetic and equilibrium data have been determined.
