摘要：

3,3'-bi(2 -pyrazolines), 4, 6 and 8, and 3,3'-bi(1,2,4-triazolo[3,4-a]isoquinolines), 13-16, have been prepared in good yields via 1,3-dipolar cycloaddition reactions of bis(arylnitrilimines), 3, with acrylonitrile, acrylamide, benzalacetophenone and 3,4-dihydroisoquinolines, 12, respectively. 3,3'-bipyrazoles 10 and 11 have been prepared in excellent yields by reaction of 3 with dibenzoylmethane and benzoylacetonitrile, respectively. The regiochemistry of the cycloadducts is discussed
