The purpose of this work is to prepare complexes of low-valent transition metals where both a phosphorus (III) and an amino groups are coordinated to the metal and to survey their catalytic properties. According to Roundhill and Rauchfuss4, such compounds could be of direct importance to homogeneous catalysis. For example, one can expect that coordination of the amino arm can confer a high electron density on the central atom. Thus, it was observed 5 that the order of effectiveness for the catalytic hydrogenation of 1-hexene is
In addition, since low-valent complexes are usually stabilized by π-acceptor ligands, it is likely that the coordinated amino group will undergo facile substitution by π-acceptor ligands. This propensity to substitution has been again demonstrated by Roundhill and co-workers 6 who reported the ready carbonylation of the complex {Rh(PN)2}PF6, where PN is o-(diphenylphosphino)-N,N-dimethyl-aniline, to {Rh(PN)2(C0)2}PF6.
