SYNTHESIS AND TRANSFORMATIONS OF CYANOMETHYL-1,2,4,5-TETRAZINES
Derivatives of s -tetrazine containing malonodinitrile, ethyl cyanoacetate, and 1,3-indanedione fragments were synthesized by the nucleophilic substitution of heterocyclic groups in 3,6-diazolyl-1,2,4,5-tetrazines. Coordination compounds of the cyanomethyltetrazine anion with Cu + , Mn 2+ , and the tetrathiafulvalene radical cation were obtained, and their structures were determined. A transformation of cyanomethyltetrazines to pyrrolo[1,2- b ][1,2,4,5]tetrazines catalyzed by metal cations was discovered. Authors: S. G. Tolshchina, R. I. Ishmetova, N. K. Ignatenko, A. V.
