TRANSITION METAL COMPLEX

摘要

Transition metal complexes of the general formula I [A]x- [Q]+xI where Q is one equivalent of a cation, x is from 0 to 2 and A is a transition metal complex of the general formula A where n is from 1 to 3, M is positively charged cobalt, rhodium, iridium or ruthenium, the ligands B are phosphonic, arsonic, phosphinic and/or arsinic acid ligands which are esterified with identical or different alcohols, one or more of these alcohol components carrying a functional group, L is the radicals R5 are identical or different radicals from the group consisting of C1-C4-alkyl and phenyl, p is an integer from 0 to 6, q is an integer from 0 to 5, and R1 is fluorine, chlorine, bromine, iodine, cyanide, isocyanide, cyanate, isocyanate, thiocyanate, isothiocyanate, C1-C4-alkyl, C1-C4-trialkyl phosphite or triaryl phosphite, are used as catalysts, or prepared in situ, in processes for the cyclotrimerization of acetylene compounds, for the catalytic hydrogenation of unsaturated compounds and for the hydroformylation of alkenes.
