  • Catalytic manufacturing method for imine having no substituent group on the nitrogen, and use for the imine produced
    Patent number: 9328069
    Abstract: The present invention relates to a method for manufacturing an imine having no substituent group on the nitrogen by using, as a catalyst, a metal complex on an organic azide compound, and more specifically relates to a method in which a metal-complex catalyst is used to produce, from an organic azide having an alpha-hydrogen, an imine having no substituent group on the nitrogen via a continuous nitrogen removal and 1,2-hydrogen transfer reaction. The imine having no substituent group on the nitrogen manufactured by means of the method of the present invention can synthesize diverse coupling products comprising amine compounds by means of reactions with diverse nucleophiles.
