摘要
Some new 3-(alkylsulfanyl)-7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4] thiadiazine were synthesized by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitrile. Orientation of the reaction has been determined by X-ray crystallography technique. The chlorine atom on the number 7 position of these products was replaced by secondary amines at reflux condition.
