Cascade reaction in a three-component system including adamantanethione, phenyl azide, and dimethyl fumarate


Mloston, Grzegorz; Romanski, Jaroslaw; Linden, Anthony; Heimgartner, Heinz (1996). Cascade reaction in a three-component system including adamantanethione, phenyl azide, and dimethyl fumarate. Polish Journal of Chemistry, 70:595-602.

Abstract

The major product of the three-component reaction with adamantanethione (1), dimethyl fumarate (6), and phenyl azide at 80°C has been determined as the 1-azabuta-1,3-diene derivative 7 by X-ray crystallography. A similar amount of the symmetric dispiro-1,2,4-trithiolane 8 was also found in the reaction mixture. The reaction with N-phenyl maleimide instead of the fumarate, yielded the known 4,5-dihydro-1,2,3-triazole derivative 9, and the three-component system with 1,3-thiazole-5(4H)-thione 10, dimethyl fumarate (6), and phenyl azide gave a mixture of imine 11, 4,5-dihydro-1,2,3-triazole-4,5-dicarboxylate 12 and the diazo compound 13. A mechanism via a cascade of reactions is proposed to rationalize the formation of 7.
