摘要：

Sn-119, N-15, C-13, and H-1 NMR spectra were studied for [2-(dimethylaminomethyl)phenyl]stannanes (RRRRSn)-R-1-R-2-R-3-Sn-4 Or (RRR2Sn)-R-1-R-2-Sn-4, where R-1, R-2, and R-3 are l-butyl, Cl or Br, the same or different, and R-4 is 2-(dimethylaminomethyl)phenyl. The occurrence of intramolecular interaction between the nitrogen and tin atoms was demonstrated based on changes in the characteristic values of the NMR parameters of these nuclides (delta(N-15), delta(Sn-119), J(Sn-119,N-15), and their interrelations, as well as on the relatively high values of the coupling constants (3)J(Sn-119,C-13(CH2)).
