Monosubst hydrazines by electrochemical - prodn

Hydrazines R-NH-NH2 (where R is alkyl, cycloalkyl or aralkyl opt. subst. by inert groups) useful as intermediates (e.g. for herbicidal pyridazones) are prepd. in good yields and high purity by electrochemically reducing N-R-N- nitroso-hydroxylamines in aqs. medium at pH - 1 to 4.5 at a cathode, the...

Summary:Hydrazines R-NH-NH2 (where R is alkyl, cycloalkyl or aralkyl opt. subst. by inert groups) useful as intermediates (e.g. for herbicidal pyridazones) are prepd. in good yields and high purity by electrochemically reducing N-R-N- nitroso-hydroxylamines in aqs. medium at pH - 1 to 4.5 at a cathode, the cathode and anode spaces being separated by a diaphragm.
