Abstract
The corresponding tetrasubstituted diquinoxalyls were synthesized by reaction of 2,2′,3,3′-tetrachloro-6,6′-diquinoxalyl with sodium methoxide, piperidine, and hydrazine. Tetrahydrazinodiquinoxalyl reacts with nitrous acid to give tetrakistetrazolodiquinoxalyl, which is also obtained by the action of sodium azide on tetrachlorodiquinoxalyl. Tetrahydrazinodiquinoxalyl undergoes cyclization with acetic acid to give tetrakistriazolodiquinoxalyl. A competitive effect of nucleophiles [CN and N(CH3)2] was observed in the reaction of tetrachlorodiquinoxalyl with cuprous cyanide in dimethylformamide.
