Thermal reaction of arylnitrenes with dimethyl sulphide, thioanisole, and tetrahydrothiophene
Abstract
The thermal decomposition of the aryl azides (1) into dimethyl sulphide (2), thioanisole (3), and tetrahydrothiophene (4) generally affords the 2-substituted anilines (5)–(7) in practicable yields by Sommelet–Hauser rearrangement of the intermediate N-arylsulphimides (11a–c) which result from arylnitrene attack at the sulphur atom of (2)–(4). This constitutes a potential synthetic procedure.
