Two series of compounds have been prepared and studied by means of 119Sn, 13C, and 1H NMR spectroscopy, viz. aryloxy- and N-heteroaryloxytris(1-butyl)stannanes and their thio analogues Bu3SnER, and diaryloxy- and di(N-heteroaryloxy)bis(1-butyl)stannanes and their thio analogues Bu2Sn(ER)2, where E means oxygen or sulfur, Bu is 1-butyl, R = phenyl, 1-naphthyl, or 8-quinolyl. On the basis of mutual comparison of NMR spectral parameters of both series of organotin compounds and their comparison with NMR spectral parameters of analogous, purely organic compounds CH3ER it is possible to discuss the consequences of the presence of tin atoms in the organotin substituents and of nitrogen heteroatoms in the aromatic systems, and the therefrom following structure of the organotin compounds studied.
