摘要
本文首次利用β-甲氧羰(或β-丁氧羰)乙基三氯化锡和醇的酯交换反应合成了一系列相应的β-烷氧羰乙基三氯化锡。并以此合成了它们与2,2′-联吡啶、1,10-菲罗啉、4,7-二苯基-1,10-菲罗啉的配合物。通过元素分析、摩尔电导、IR、UV、~1H NMR等对上述化合物进行了表征,提出了β-烷氧羰乙基三氯化锡分子内Lewis酸催化的酯交换反应机理。
β - Alkoxycarbpnylethyltin trichlorides were synthesized by usingtransesterifi - cation reaction of β - methoxycarbonylethyltin of β - butoxycarbonylethyltin trichloridewith alcohols for the first time. Complexes of β - alkoxycarbonylethyltin trichlorides withneutral ligands such as 2,2' -bipyrdey, 1, 10 - phenanthroline, 4, 7 - diphenyl.- 1,10 - phenanthro - line were prepared. Their structres were characterized by elemental analysis, milar conduct - ance, IR, UV, and 1H NMR spectra. The intramolecular Lewis acid catalytic transesterification mechanisms of β -alkoxycarbonylethyltin trichlorides were suggested.
