Abstract

PURPOSE: To obtain the title compound useful as foaming agents or radical polymerization initiators in a high yield readily, by reducing a coupling product between an aminonitrile and a metal hypohalogenite with a reducing agent, e.g. a nitrite.
CONSTITUTION: An aminonitrile is coupled with a metal hypochlorite in a heterogeneous solvent consisting of an aqueous and an organic phases at -5W30°C. The reaction mixture is reduced with a nitrite, succinic acid, or hydroxyl amine under acidic conditions of pH≤6 in a short time, and oily impurities are removed to give a crystalline azo compound readily without requiring the purification step. Benzene or an acetate may be cited as a solvent for forming the organic phase.
