摘要：

Arylazoaminopyrazoles (1a-d) reacts with tetracyanoethylene (TCNE) to yield pyrazolo[1,5-a]pyrimidines (9) via charge-transfer (CT) complex formation. The effect of the substituents on the basicity of the pyrazole nucleus as well as the complexation centre in different types of pyrazoles is discussed.
