kinetics of the Beckmannrearrangement of acetophenoneoximes have been measured over the acidity range 70–98% sulphuricacid. A study of the rearrangement of ortho-substituted acetophenoneoximes has shown that an N-arylnitrilium ion is an intermediate in the rearrangement. Comparison of the rates of the rearrangement of 2,4,6-trimethylacetophenone oxime in sulphuric and perchloric acids indicates that
