Controlling the coordination mode of 1,4,7-triazacyclononane complexes of rhodium and iridium and evaluating their behavior as phenylacetylene polymerization catalysts

摘要

A number of kappa(1)- and kappa(3)-triazacyclononane Rh-I, Ir-1, Rh-III, and Ir-III derivatives have been synthesized and characterized, with conversion from kappa(1)-triazacyclononane complexes to kappa(3)-derivatives. The results of the catalytic studies show that the Rh(I) and Ir(I) complexes polymerize phenylacetylene more effectively than [M(COD)(mu-Cl)](2) (M = Rh and Ir).
