PYRROLOTETRAZOLES AND RING-FUSED DERIVATIVES

摘要

The preparative chemistry of seven types of pyrrolotetrazoles(formally:pyrrolo[1,2-d]tetrazoles)A-G including five ring-fused derivatives such as B',B",C,C",and E'is surveyed in this article.Theoretical work on annular tautomerism and pyrrolotetrazole-azidopyrrole isomerism is dealt with complementarity.
