Abstract
Benzo‐1,3‐tellurazoles carrying alkyl or aryl substituents in position 2 were prepared in a facile two‐step sequence, starting with readily available 2‐haloanilines. This approach relies on the preparation of bis(2‐aminophenyl) ditellurides by nucleophilic halide displacement from 2‐haloanilines with sodium telluride in N‐methylpyrrolidone. Subsequent reductive cyclization with carboxylic acid halides or carboxylic anhydrides furnished benzo‐1,3‐tellurazoles in good yields.
