Abstract
Symmetrically and unsymmetrically substituted secondary and tertiary amines are selectively prepared in high yields by a one-pot multiple alkylation procedure from ammonia or primary amines with styrenes and/or cyclic olefins, carbon monoxide and hydrogen in the presence of [Rh(cod)Cl] 2 as catalyst. Similarly unsymmetrically substituted tertiary amines are obtained under hydroformylation conditions from primary amines by a one-pot reductive bisalkylation procedure using preformed aldehydes or ketones in one step and the hydroformylation products in the second step of a combined amine condensation - reduction - hydroaminomethylation reaction sequence.
