NITROGEN-TELLURIUM-CONTAINING HETEROCYCLES. 3. REACTION OF 2-PHENYLBENZOTELLURAZOLE AT THE HETEROATOMS
Reactions of 2-phenylbenzotellurazole at both heteroatoms are studied. ?-Telluranes and molecular complexes with mercury and palladium salts are prepared.Exchange of a tellurium atom by sulfur is achieved.Alkylation of a heteroatom of the pyrrole type, the tellurium atom, is achieved in a series of benzazoles for the first time.

Nitrogen-Tellurium Heterocycles. 1. Preparation of Benzotellurazoles and Their Derivatives
Cyclization of previously isolated and purified N-acyl derivatives of α-methyltelluroaniline under the influence of POCl3 leads to 2-R-benzotellurazoles in yields of 35-65percent. 1,1-Dichloro-2-R-benzotellurazoles are intermediates in this reaction.
