Tertiary α,Ï-diamines are selectively prepared in high yields by the reaction of α,Ï-diolefins with secondary amines, carbon monoxide and hydrogen in the presence of [Rh(cod)Cl]2 as a catalyst precursor. This one-pot synthesis proceeds via a hydroformylation-amine condensation-reduction sequence and leads to a mixture of n,n-, n,iso-, and iso,iso-products.
Starting from diallylethers, -silanes, or -amines various di- or triamines with potential biological activity are obtainable in one step by RhI-catalysed hydroaminomethylation of the alkene moieties in the presence of synthesis gas.
