Synthesis of some new organotellurium compounds based on 1-substituted tetrazole

New organotellurium compounds are derived from 1-butyl-5H-tetrazole (1). 1-butyl tetrazole-5-yl mercury (II) chloride (2) was synthesized from the reaction of compound 1 with mercury acetate and sodium chloride. The 1:1 and 1:2 ratio reactions of tellurium tetrabromide with compound 2 gave 1-butyl tetrazole-5-yl tellurium tribromide (3) and di (1-butyl tetrazole-5-yl) tellurium dibromide (4), respectively. The reduction of compounds 3 and 4 by the alcoholic solution of aqueous hydrazine gave di (1-butyl tetrazole-5-yl) ditelluride (5) and di (1-butyl tetrazole-5-yl) telluride (6), respectively. The reaction of compound 5 with iodine and thionyl chloride gave 1-butyl tetrazole-5-yl tellurium triiodide (7) and 1-butyl tetrazole-5-yl tellurium trichloride (8), respectively. The reaction of compound 6 with iodine and thionyl chloride gave di (1-butyl tetrazole-5-yl) tellurium diiodide (9) and di (1-butyl tetrazole-5-yl) tellurium dichloride (10), respectively. The prepared compounds were characterized and the molar conductivities proved that the compounds 2–3 and 7–10 behaved as electrolytes (1:1).
