摘要：

2,3-Dicyano-1,4-naphthoquinone (DCNQ), the easily obtainable isomer of 2-(dicyanomethylene)indane-1,3-dione (CNIND), reacts with arylazo-, pyridylazo- and arylaminopyrazoles 1-3 via charge-transfer (CT) complexation to yield pyrazolo[2,3-a]quinazolinediones 10a-f and pyrazolo[2,3-a]quinazolinyl acetates 11a-e. Furthermore, aminopyrazole 3 reacts with 2,3-dichloronaphthoquinone (DCHNQ) to afford the naphthoquinoimidazopyrazole 13. The mechanism of the formation of products 10 and 11 is discussed.
