An important intermidiate 2-butyl-4-chloro-5-(4-bromomethyl phenoxy) pyridazinone 3 was first obtained from 4,5-dichloropyridazinone using two different methods. Compounds 4a～4l were synthesized by the reaction of 3 with different oximes.

从2-叔丁基-4，5-二氯哒嗪酮出发，以两种方法合成了中间体2-叔丁基-4-氯-5-(4-溴甲基苯氧)哒嗪酮(3)。3与肟反应合成了含哒嗪酮的苄基肟醚类化合物4a～4l。

The effects of organic solvent, temperature and water activity were also investigated in PS IM catalyzed tranesterification of 2-chloro-1-phenylethanol with vinyl acetate.
