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

The stoichiometric reaction of [Pd{PhP(C6H4-2-S)2}(PPh3)] (1) with Ph2CH2CH2Ph2 in dichloromethane (CH2Cl2) as solvent, affords complex [Pd{PhP(C6H4-2-SCH2Cl)(C6H4-2- S)}(Ph2PCH2CH2PPh2)]Cl (2). This specie, being the result of the nucleophilic reaction of a de-ligated thiolate moiety from the fragment [Pd{PhP(C6H4-2-S)2}] with dichloromethane (chloromethylation).
