Synthesis and characterization of [Pd{PhP(C6H4-2-SCH2Cl)(C6H4-2-S)}(Ph2PCH2CH2PPh2)]Cl: An example of hemilability and dichloromethane activation

The reaction of [Pd{PhP(C6H4-2-S)2}(PPh3)] (1) with Ph2CH2CH2Ph2 in dichloromethane affords complex [Pd{PhP(C6H4-2-SCH2Cl) (C6H4-2-S)} (Ph2PCH2CH2PPh2)]Cl (2) as product of the phosphine substitution, the hemilabile properties of the ligand [PhP(C6H4-2-S)2]2− and the CH2Cl2 activation by the de-ligated thiolate moiety.
