Phosgene → 2-Phenoxycarbonylhydrazinecarbonyl chloride

Participants

Reaction Steps

Example 1 was repeated but substituting phenyl carbazate (77.3, 0.57 mole) for the ethyl carbazate and using phosgene (50 ml, 0.7 mole) in dry dichloromethane. 2-Phenoxycarbonylhydrazinecarbonyl chloride was isolated as impure solid (42 g, 54%) mp 76°-80° C. decomp., whose ir spectrum was consistent with the named compound being the major component.
