REACTIONS OF 3,5-DIAMINO-4-ARYLAZOPYRAZOLES WITH CHLORINATED QUINONES

3.5-Diamino-4-arylazopyrazoles 1a-d reacted with 3,4,5,6-tetrachloro-1,2-benzoquinone(CHL-o) via charge-transfer (CT) complex formation giving bisimidazobenzobispyrazoles 5a-d.On mixing either 2,3,5,6-tetrachloro-1,4-benzoquinone(CHL-p) or 2,3-dichloro-1,4-naphthoquinone(DCHNQ) with 1a-d in DMF, pyrazoloquinazolinetrione 8a-d and 9a-d derivatives were formed.
