摘要

C (3), C (1), and (CH3) 3Sn-(108.49 6, 17.41 6, and-10.78 6) broadened while that for C (2)(137.74 6) remained sharp. At-20" C only signals for C (2)(137.34 6), Et20, and Me4Sn (- 9.71 6) were visible. Upon recooling to-80" C the 13C NMR spectrum showed that the sample had undergone redistribution of the allyl groups. Thus signals for three different allyl species could be seen along with methyl resonances for Me4Sn (-9.71 a), 1 (-10.77 6), ...
