Abstract	An anchimeric assistance of anilide in the rearrangement of dichloro-1,4-oxathaines 1 to 2-chloromethyl dihydro-1,4-oxathiins 2 is described. The inductive effect of the carbonyl group of anilide was negligible in the rearrangement. A rate of the rearrangement depended on the basicity of anilide nitrogen. A hydrogen bonding between the anilide hydrogen and an oxygen atom of those substituents make the nitrogen less basic, resulting in the slower rearrangement.
