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

Article abstract of DOI:10.1007/BF00472631

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.
