摘要

Abstract The palladium-catalysed carbonylation of ethene in methanol shows acute sensitivity towards the diphosphine ligand used. Systems based on 1, 3-bis (di-t- butylphosphino) propane afford catalysts for fast, selective methoxycarbonylation to methyl propionate; the corresponding catalyst based on 1, 2-bis (di-t-butylphosphino) ethane hydroacylates ethene to diethyl ketone at high rates. The use of less sterically demanding ...
