of 1Bu2Sn(NSN′Bu)2, 4a, two configurational isomers are present in solution, but only one in the solid state. In the case of the tin compounds, all NMR data point towards association both in solution (at low temperature) and in the solid state, the tendency for association being greatest for n-butyl-tris(N-tert-butylsulfurdiimido)tin (6a).
摘要 双(硫二亚胺)锡(1a-5a, 3b, 4b)和三(硫二亚胺)元素化合物(元素= Si, Ge, Sn; 6a, 7a,b-9a,b)在溶液(1H、13C、15N、29Si、119Sn NMR)和固态(13C、15N、119Sn CP/MAS NMR)。就快速 E/Z = Z/E 异构化而言,所有化合物都是溶液中的流动分子。在 N-叔丁基衍生物的情况下;各个异构体的构型可以通过低温 NMR 测量来确定。例如,在 1Bu2Sn(NSN'Bu)2, 4a 的情况下,溶液中存在两种构型异构体,但只有一种呈固态。在锡化合物的情况下,所有 NMR 数据都指向在溶液(低温)和固态下的缔合,
