Oxidative addition of acetyl chloride to the compound [RhCl(PPh3)3] leads to the formation of two acetyl- and one methyl-rhodium species, all isomeric, before reductive elimination of methyl chloride occurs to give [RhCl(CO)(PPh3)2]. The structures of all the compounds have been determined using i.r. and both 1H and 31P n.m.r. spectroscopy. The effects of changing the nature of the acid halide and the tertiary
