When 4,5-dichloro-3-pyridazone, 4,5-dibromo-3-pyridazone, or 4,5-dichloro-2-phenyl-3-pyridazone in methanol was allowed to react with 95% hydrazine, a mono-halo mono-hydrazino-3-pyridazone was obtained. An unequivocal proof of structure for 4-chloro-5-hydrazino-3-pyridazone is reported. Twenty-five hydrazones of 4-bromo-5-hydrazine-3-pyridazone and twenty-seven hydrazones of 4-chloro-S-hydrazino-3-pyridazone were prepared. One cyclized derivative of 4-chloro-5-hydrazino-2-phenyl-3-pyridazone is also reported. |
