Abstract
New nonadienylamines, nonatrienylamines and nonylamines are described, as well as a new process for their manufacture by reacting a 1,3-diolefine with a Schiff's base in the presence of certain nickel catalysts. The new compounds are suitable for combating micro-organisms, for example in the protection of materials.
