摘要：

The treatment of technically available 2-(chloroethyl)phosphonic acid dimethylester (1) with diphenylphosphine and potassium-tert.-butylate affords 2-(diphenylphosphino)ethylphosphonic acid dimethylester (2 a) in a simple way. 2 a can be used as a hemilabil complex ligand (by phosphine and phosphoryl group.) Rhodium complexes of the type (MeO)2P(O)CH2CH2P(Ph)2RhL3 (3) were obtained from 2a and exhibit excellent catalytic properties in the liquid-phase carbonylation of methanol to acetic acid. Studies on other chelat-ligands did not confirm the exceptional increase of the activity by bisphosphinemonoxyd-ligands and the inhibition of the title reaction by bisphosphine-ligands already published.
