Abstract
First-order kinetics of the title rearrangement to 3-acetoxy-1-acetyli ndazole (2a), complete exchange of O-acyl groups in cross-experiments, insensitivity to change in reaction medium, lack of electronic substi tuent effects and activation parameters are considered as evidence in favour of a pericyclic mechanism through C=(OC)-C-..... close contacts .
