【Abstract】 Two kinds of Pyridazinones including 5 hydrazino pyridazinones 3a～3j and 5 pyrazolepyridazinones 5a～5d were synthesized. The important intermediate 2 tert butyl 4 chlorol 5 hydrazion3(2H)pyridazinone was first obtained and the reaction conditions were discussed. Preliminary bioassay results indicated that some of these compounds possessed fungicidal and plant growth regulative activities.$$$$更多还原
