Carbon monoxide catalyses trans to cis isomerisations of (L = tertiary phosphine) in chloroform solution.The process involves formation of five-co-ordinate intermediates from which halide or tertiary phosphine can be eliminated, giving trans-(1+) or cis- respectively.Structure changes appear to be by pseudo-rotations rather than by consecutive displacements.A number of isonitrile complexes undergo similar reactions.Halide-bridged cations (2+) formed by halide extraction from cis- by Ag(1+) enter rapid (n.m.r. time-scale) exchange processes with the latter complexes at ambient temperatures.Halide elimination from cis- by solvent chloroform appears to initiate the process.The trans isomers do not participate in the exchange.
