Document Type and Number:

WIPO Patent Application WO1992018564

Kind Code:

A3

Abstract:

A method of manufacturing 3-amino-2-cyclohexene-1-one by hydrogenating m-phenylenediamene to produce a novel intermediate salt of 3-amino-2-cyclohexene-1-imine followed by hydrolysis to produce 3-amino-2-cyclohexene-1-one. The novel intermediate 3-amino-2-cyclohexene-1-imine has also be isolated.
