The cycloaddition of a series of C-acetyl-N-arylnitrilimines 6a-e to acrylamide (2a), acrylonitrile (2b), and substituted benzylideneacetophenones 4a-d has been studied.Under thermal conditions, these 1,3-dipolar cycloadditions proceed with absolute regio

Reaction of nitrilimines 2 with fumaronitrile 6 yielded 4-cyanopyrazoles 8 in good yields.The structures of 8 were substantiated by comparison with their regioisomers 5-cyanopyrazoles 5, prepared by addition of 2 to acrylonitrile followed by oxidation of
