Abstract
Abstract Synthetic and spectral ( 1 H, 13 C and 31 P NMR) details are presented for the formation of cyclometallated palladium(II) and platinum(II) dimers by reaction of trimesitylphosphine with MCl 2 and MCl 2 Y 2 (M Pd, Pt; Y CH 3 CN, PhCN, 1 2 COD) and for the corresponding halide metathesis products. These dimers are very stable with a strong MC bond. There were no non-cyclometallated products isolated and cyclopalladation is definitely more facile than cycloplatination. The latter two observations are unusual with respect to the known reactivity of phosphines with palladium(II) and platinum(II) centres. Geometric isomerism is observed for the Pt species.
