Direct functionalization of 4,5-dichloropyridazin-6-one with some nucleophiles in seven solvents gave regioselectively 5-halo-4-substituted-pyridazin-6-ones as main product. Reaction of 4,5-dichloropyridazin-6-one with 2-mercaptopyrimidine (2 equivalents) also afforded 4,5-di(pyrimidin-2-ylsulfanyl)pyridazin-6-one as the main product.
用一些亲核试剂在7种溶剂中对4,5-二氯哒嗪-6-一个分子进行直接官能化,得到区域选择性的5-卤代-4-取代的哒嗪-6-作为主要产物。4,5-二氯哒嗪-6-1与2-巯基嘧啶(2当量)的反应也得到4,5-二(嘧啶-2-基硫烷基)哒嗪-6-1为主要产物。
