6-(4-卤代苯基)-3(2H)-哒嗪酮的合成

Synthesis of 6-(4-helophenyl)-3(2H)-pyridazinones

从原料卤苯和琥珀酸酐开始 ,经Friedel-Crafts反应、环合反应及脱氢反应合成了 6 - ( 4-卤代苯基 ) - 3( 2H) -哒嗪酮 ,其结构经IR、1HNMR及元素分析所证实 .

From starting material halobenzene and succinic anhydride, 6-(4-halo- phenyl)-3(2H)-pyridazinone were synthesized by Friedel-Crafts reaction, cyclization and dehydrogenation. Their structures were confirmed by IR, 1HNMR and elementary analysis.
