The reaction of a series of 2,3-epoxy alcohols and the corresponding formates, acetates, and benzoates promoted by Cp 2 TiCl has been studied. The different outcome of the reaction of epoxy derivatives has been rationalized in terms of mechanistically biased processes. After homolytic oxirane cleavage, four main types of reaction were found: dehydroxylation, decarboxylation, dehydrogenation, and deoxygenation
已经研究了由 Cp 2 TiCl 促进的一系列 2,3-环氧醇和相应的甲酸酯、乙酸酯和苯甲酸酯的反应。环氧衍生物反应的不同结果已根据机械偏向过程进行了合理化。在均裂环氧乙烷裂解后,发现四种主要反应类型:脱羟基、脱羧、脱氢和脱氧。反应产物根据取代模式而变化。证明了这些消除的根本性质。
