Three mixed diorganotin dichloride have been synthesized by the reaction of tetraorganotin RSnPh3(R=Me3SiCH2、EtMe2SiCH2、Bu)with concentrated hydrochloric acid.

Triphenylphosphine oxide)dibenzyltin dichloride was synthesized by the reaction of dibenzyltin dichloride with triplhenylphosphine oxide and characterized by elemental analysis.

The reaction of benzylchloride with tin suspended in boiling xylene in the presence of catalytic water directly affords dibenzyltin dichloride(1) in the yield of 90%,and compound (1) reacts with triphenyl phosphine oxide to give the corresponding complexe(2) in the yield of 95%.
