Abstract The aminomethylation of ethylene with a primary amine has been shown to provide a highly selective route to n-propylamines; the rhodium catalysed reaction of n-propylamine with ethylene and syngas (2/1, H 2/CO) affords di-n-propylamine with 98% selectivity (with respect to ethylene). The reaction of amines of the type RR 1 NH with the ethylene/syngas mixture and a rhodium catalyst provides a highly selective and general route to the n- ...
