摘要：

[GRAPHICS] Novel methods for the preparation of organotellurium heterocycles derived from bis(2-aminophenyl) ditelluride were developed. Thus, highly nucleophilic 2-aminobenzenetellurol generated by reduction in situ reacted smoothly with malonitrile to 2-cyanomethylbenzo-1,3-tellurazole, while its treatment with carbon disulfide and subsequent methylation generated 2-methylmercaptobenzo- 1,3-tellurazole. Amidation to ( 2-haloacetamidophenyl) ditellurides, followed by reduction under carefully controlled conditions, furnished previously inaccessible 2H-1,4-benzotellurazin-3(4H)-ones in yields ranging from 47- 62%.
