Abstract
The hydrogenation of iminonitriles and iminobisnitriles of type 1a–f is a particularly difficult process as the intermediate dieneamines are highly susceptible to addition reactions. A short general method of preparation and purification of 2‐aminomethylene‐1,3‐diamine of type 2a–e by catalytic hydrogenation of iminobisnitriles is described.
