Cleavage reactions of iodinehalides, -pseudohalides IX (X = Cl, Br, NCO, NCS, N3 and CN) with Ph3SnCp yield triphenyltinhalides, -pseudohalides (Ph3SnX) indicating cleavage of Cp-Sn bond in preference to Ph-Sn bond, and cleavage reactions of iodine carboxylates IX′ (X′ = CH3OCO, C5H5OCO, C6H5CH2OCO, o-NH2C6H4OCO, o-CIC6H4OCO, p-NO2C6H4OCO, p-NH2C6H4OCO, C6H5CH =CHOCO) (in situ) with Ph3SnCl give hitherto unknown diphenylchlorotin carboxylates (Ph2SnX′Cl) indicating cleavage of Ph-Sn bond in preference to Cl-Sn bond. On the basis of the results, it is predicated that these diphenylchlorotin carboxylates possess bridging carboxylate groups (inter-molecularly chelated structure) in the solid state, whereas in solution they contain chelated carboxylate groups (intra-molecularly chelated structures).
