NITROGEN-TELLURIUM HETEROCYCLES. 2. APPROACHES TO THE SYNTHESIS OF 2-SUBSTITUTED BENZOTELLURAZOLES

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.

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.
