Article abstract of DOI:10.1039/DT9890001193

The ligands Ph2PCH2CRR'OH form complexes of stoicheiometry PdCl2(Ph2PCH2CRR'OH)2 which are in the neutral form trans- where R,R' = Me or H (2a)-(2c) in CDCl3 solution, and the ionic form where R = R' = Me (4a) or R = Me, R' = H (4b) in CD3OD solution.The complex dissolves in D2O to give an acidic solution of pH 3.9.Treatment of trans- (2a) or (2b) with AgClO4 in acetone gives (6a) or (6b).Deprotonation of (6a) or (6b) with Et3N in CDCl3 or deprotonation of (2a)-(2c) with NaOH in ethanol gave the bis(alkoxo) complexes (7a)-(7c).Deprotonation of (2c) with Et3N in CDCl3 gave a mixture of three Pd species, including the binuclear complex (9).All products have been characterised by a combination of elemental analysis, i.r., (1)H, and (31)P n.m.r. spectroscopy.
