| Abstract: | Summary
Trans-RhCl(CO)(PR3)2] complexes PR3=tris-(2-pyridyl)phosphine {P(2-pyl)3}, phenylbis(2-pyridyl)phosphine {PPh(2-pyl)2} or tris(3-pyridyl)phosphine {P(3-pyl)3}] have been synthesized and examined by spectroscopic methods (i.r., u.v.-vis,31P{1H} n.m.r.,1H n.m.r.). In solution the P(2-pyl)3 and PPh(2-pyl)2 complexes exhibit equilibrium between the pentacoordinate state, with one of the phosphine molecules coordinated via nitrogen and phosphorus, and complexes with the phosphine coordinated only through nitrogens. |
