✦ Synopsis

Multinuclear NMR data ('H, 13C, '19Sn) have been obtained for almost all possible isomers of the composition Me3Sn(C3H,)SnMe3 ( m = 2,4,6) and Me3Sn(C,H,)SnMe3 (n = 0,2,4,6,8). The coupling constants xJ(Sn, Sn) (x =4,5) are not linearly related to the corresponding coupling constants "J(H, H), but are particularly large when tin-carbou bonds can interact hyperconjugatively with carbon-carbon double or triple bonds.

We propose the 13 C-detecting 1D DEPT long-range C-C relay to detect super long-range H-C connectivity via four bonds ( 1 H-13 C-X-X-13 C, X represents 12 C or heteronuclear). It is derived from the DEPT C-C relay which detects the H-C correlations via two bonds ( 1 H-13 C-13 C) by setting the delay
