## Abstract Attempted epoxidation of long‐chain α,β‐unsaturated esters resulted in the formation of the rearranged products of the corresponding epoxyesters. It was observed that reaction of peracids with esters of C~16~, C~18~ and C~22~ trans‐2‐enoic acids, instead of yielding the expected epoxide
