Pd2I2(μ-I)2(dmpm)2 and Me2S, whereas alkylation of 2a with MeOTf generates the cationic, bridged-methanethiolato complex [Pd2Cl2(μ-SMe)(dmpm)2]OTf (5). Oxidation of 2a with m-CPBA forms a mixture of Pd2Cl2(μ-SO)(dmpm)2 and Pd2Cl2(μ-SO2)(dmpm)2, whereas Pd2Br2(μ-S)(dmpm)2 reacts selectively to give Pd2Br2(μ-SO)(dmpm)2 (6b). Treatment of the Pd2X2(μ-S)(dmpm)2 complexes with X2 (X = halogen) removes the bridged-sulfide
