Abstract
Carbazates (NH2‐NH‐COOR) are easily obtained by action of hydrazine hydrate on organic carbonates. The carbazates react with active halogen compounds to form disubstitution products of the type R′R′N‐NH‐COOR. Suitable cleavage of these derivatives leads to asymmetrical disubstituted hydrazines R′R′N‐NH2.Reactions of the ethyl, allyl, methallyl, β‐hydroxyethyl, t‐butyl, benzyl, and phenyl carbazates have been studied.Keywords
