Twenty four triphenyltin derivatives of substituted benzoic acids have been synthesised. On the basis of i.r., 119Sn n.m.r., and Mössbauer spectroscopic data, structures have been assigned to these compounds as either tetrahedral monomers or trans-SnR3O2 polymers. The choice of structure in these systems is dictated by both steric and electronic effects, and for two compounds (2,6-dichloro- and 2-nitro-benzoates)
已经合成了二十四个取代苯甲酸的三苯基锡衍生物。根据ir,119 Sn nmr和Mössbauer光谱数据,已将这些化合物的结构指定为四面体单体或反式-SnR 3 O 2聚合物。这些系统中结构的选择取决于空间效应和电子效应,对于两种化合物(2,6-二氯-和2-硝基-苯甲酸酯),证据表明两种结构均同时存在。讨论了影响优选结构的因素。
