Abstract

1 A study has been made of the action of hydrazine and methylhydrazine on ortho- and para-chloronitrobenzenes, 1:4-dichloro(bromo)-benzene and 1-chloro- or 1-bromo-3:4-dinitrobenzene. 2 The Phenylhydrazine derivatives obtained in these reactions, viz. 2-nitro- and 4-nitrophenyl-α-methylhydrazines, 2-nitro-4-chloro- and bromophenyl-α-methylhydrazines, 2-nitro-5-chloro- and bromo-phenylhydrazines were investigated as reagents for aldehydes and ketones.

Study Snapshot

Hydrogen and methylhydrazine react with ortho- and para-chloronitrobenzenes, producing 2-nitro- and 4-nitrophenyl--methylhydrazines, which can be used as reagents for aldehydes and ketones.

The action of hydrazine, methylhydrazine and dimethylhydrazine on some halogenonitrobenzenes

Hydrazine, methylhydrazine, and dimethylhydrazines can produce compounds useful as reagents for aldehydes and ketones by reacting with various halogenonitrobenzenes.

Mechanism study of base-catalyzed cyclization of 2-nitrophenylhydrazine in aqueous solution

Base-catalyzed cyclization of 2-nitrophenylhydrazine to 1-hydroxybenztriazole in alkaline aqueous solutions involves direct attack of the -hydrazino nitrogen on the nitrogen of the nilro group with elimination of water.
