摘要：

Kinetic data for the epoxidation of a series of alpha,beta-unsaturated esters, 2-10, by dimethyldioxirane in dried acetone are reported. These epoxidations are less sensitive to steric effects and occur with lower k(2) values than those for simple alkenes. Relative reactivity could be modeled based on a spiro transition state mechanism. The density function calculations were in good agreement with the km values except for those compounds with cis-beta-substituents.
