摘要：

Condensation of 1-arylhydrazono-1-benzotriazol-1-yl 2-propanones (5a-c) with DMF DMA afforded 1-aryl-3-benzotriazol-1-yl-1,4-dihydropyridazine-4-ones (8a-c). While condensation of 1-functionally substituted methylbenzotriazoles 3b,c with 2-arylhydrazono-3-oxoarylpropanal 13a,b give 3-aroyl-5-(benzorriazolyl-1-yl)-1,6-dihydro-1-phenylpyridazine-6-ones and 6-imines 14a-d.
