Del re calculations have been extended to correlate and interpret the NMR data in the organotincompounds. The methyl proton chemical shifts have been correlated with the partial charge on the methyl hydrogen atom. Variations in 13CH and tin-proton coupling constants have been correlated with the calculated Coulomb integral values, and the relationship has been interpreted in terms of the change in
Del re计算已扩展到可以关联和解释有机锡化合物中的NMR数据。甲基质子化学位移已与甲基氢原子上的部分电荷相关。在变型13 CH和锡-质子偶合常数已被相关与计算出的库仑积分值,和所述关系已经在变化的形式进行了解释小号的个字符数相应的原子等价使用杂交参数连同轨道计算的理论量。

Complexes of GroupIVBelements and metal carbonyls of general formulae [R2MFe(CO)4]2, [R2MFe(CO)3PPh3]2, and R2M(C⋮C·R′)2[Co(CO)3]4(where R,R′= alkyl or aryl; M = Si, Ge, and Sn) have been obtained from the reactions of alkynyl compounds of GroupIVBelements with metal carbonyls. The preparations, properties, and reactions of the secomplexes are described. The structures are inferred from infrared
