本文报道了在DMSO溶剂中利用Bordwell指示剂重迭法测定六种高配位双环氮氧杂有机锡化合物的α-CH的酸性离解常数(pKa)的方法, 并对配合物的结构与其α-CH酸性的关系进行了讨论。

The α-CH acidities of the amino acid fragments in the high coordinate bicycloazastannoxide (4) were determined. This was carried out by Bordwell indicator overlapping method in DSMO solution. The relationship between the structures of such organotin (4) complexes and their α-CH acidities are discussed.
