On the other hand, the good yields of the complexes of composition Me2SnCI2-x(OAr)x and n-Bu3Sn(OAr) have been obtained from the reaction of Me2SnCl2 and n-Bu3SnCI with 2-phenylphenol in the presence of Et2NH in tetrahydrofuran. The characterization of the complexes has been accomplished by elemental analyses, molar conductance measurements, molecular weight determinations and IR, 1H, 13C, 119Sn NMR and mass spectral methods. The thermal behaviour of the complexes has been studied by TG-DTA techniques. The reactions of parent complexes with nitrogenous bases viz. imidazole and benzimidazole have yielded 1 : 1 and 1 : 2 molecular adducts authenticated by physicochemical and IR spectral data. |
