Abstract
Intermolecular charge‐transfer (CT) complexes of arylazoaminopyrazoles as donors with 2‐(dicyanomethylen)indane‐1,3‐dione (CNIND) and 9‐(dicyanomethylene)‐2,4,7‐trinitrofluorene (DTF) as π‐acceptors have been investigated spectroscopically. Arylazoaminopyrazoles react with CNIND via charge‐transfer complexes to yield indanopyrazolo[1,5‐α]‐pyrimidines 5.Keywords
