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.

Several 2-substituted benzotellurazoles have been prepared by the reaction of N-allyl derivatives of o-methyltelluroaniline with POCl3 or SOCl2 followed by reduction of the ?-telluranes which are formed.The use of the zinc and sodium salts of o-aminotellurophenol and 2-chlorotellurenylazobenzene, in a procedure similar to that used to prepare benzothiazoles and benzoselenazoles, did not lead to the formation of benzotellurazoles.
