Resumo

Hexamethylphosphoramide (HMPA) adducts of the type Ph3PbX·HMPA (XCl, Br, I, and NCS), Ph2PbX2·2HMPA (XCl, Br, and I), and Ph2PbX2·HMPA (XBr and I), have been prepared and characterized by infrared, Raman, mass, and 31P nmr spectroscopy. Molecular weight and infrared solution data show that Ph3PbX·HMPA adducts dissociate in benzene, the degree of dissociation being NCS«Cl<Br I-Br>Cl for Ph3PbX·HMPA adducts. Corresponding tin and lead adducts are compared with respect to mode of adduct formation.
