Treatment of Pd(tmeda)Me2 with dimesitylphosphine (PMes2H, L) gave cis-PdL2Me2 (1). trans-ML2Cl2 (M = Pd (2), Pt (3)) were prepared from a variety of starting materials. The reaction of Pt(cod)Cl2 with L gave cis-PtL2Cl2 (4), which reacted with PPh3 to yield cis-Pt(L)(PPh3)Cl2 (5). cis-PtL2(Me)(Cl) (6) was prepared from L and Pt(cod)(Me)(Cl), while reaction of L with Pt(cod)(Et)(I) gave cis-PtL2(Et)(I) (7), which isomerized to trans-PtL2(Et)(I) (8). The phosphine-borane PMes2H·BH3 (9) was made by reaction of L with BH3·SMe2. Crystal structures of 2·2CH2Cl2, 4·CH2Cl2, 5·2CH2Cl2, 6, and 9 provided 7information on the steric bulk of L (cone angle ca. 149°). Restricted rotation about the Pt-P and P-C bonds in complexes 4-8 was studied by variable temperature NMR spectroscopy.
