Preparation and X-ray crystal structure of 2-iodyl-N,N-dialkylaniline oxides: first entry into the heterocyclic system of benziodoxazole.

The oxidation of 2-iodo-N,N-dialkylanilines with an excess of dimethyldioxirane in acetone affords 2-iodyl-N,N-dialkylaniline oxides, structural features of which are in agreement with the new heterocyclic system of benziodoxazole.
