(A) Abs–time curves for the reaction of [PtMe2(pbt)], 1a, (3 × 10–4 M) with PhCH2Br (0.006–0.015 M, concentration increases reading downward) in toluene at 25 °C. (B) Plots of first-order rate constants (kobs/s–1) versus concentration of benzyl bromide for the reaction of (a) [PtMe2(pbt)], 1a, with PhCH2Br in toluene; (b) [PtMe(PPh2Me)(ppy)], 1b, with MeI in acetone; (c) [PtMe(PPh2Me)(ppy)], 1b, with PhCH2Br in acetone; and (d) [PtMe(PPh2Me)(bhq)], 1c, with PhCH2Br in acetone at T = 40 °C.
