Abstract

o-Iodopropiolanilides (3) reacted with sodium hydrogen telluride to give 1,5-benzotellurazepinones (5) via intramolecular cyclization of the presumable phenyltellurole intermediates (4). The lactams (5) were converted into the title lactim compounds, 4-methoxy-1,5-benzotellurazepines (7) by treatment with trimethyloxonium tetrafluoroborate.
