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。
This paper presents antimalarial activity of several triphenyltin(IV) aminobenzoate compounds synthesized from the reaction of triphenyltin(IV) hydroxide with 2-, 3-, and 4-aminobenzoic acid. The activity of the compounds as anti-malaria agents was evaluated using Plasmodium falciparum, and demonstrated that the compounds have about the same IC50 with that of chloroquine (2×10−3 μg/mL) applied as the

Organotin clusters and cages have been synthesized in quantitative yields by using a benign solventless synthetic methodology. Using this method a variety of structural forms, which include the drum, O-capped cluster, tetranuclear oxo cage, discrete, and polymeric compounds, have been synthesized. All these compounds (1-11) have been characterized by spectroscopic and analytical techniques. The new compounds, which include the hexameric drum [n-BuSn-(O)OCOAd](6) (Ad = adamantyl) 9, a triorganotin-based discrete structure Ph3SnO2C-C(6)H(2-)2,4,6-Me-3 (10), and a polymer Ph3SnOSO2-C6H3-2,5-Me-2 (11), have been characterized by single-crystal X-ray crystallography.
