The selective preparation of aliphatic primary amines from an olefin, synthesis gas (CO/H{sub 2}) and ammonia has been developed involving the use of homogeneous catalysts comprising cobalt octacarbonyl, phosphine ligand, and an ether or acetamide solvent system. 1-Hexene oxoamination typically yields a mix of C{sub 7} plus C{sub 14} primary amine in 57% selectivity. Process parameter studies involving changes in [NH{sub 3}], [Co], P/Co molar ratios, H{sub 2}/CO ratios, etc. provide some insight into the mechanism of this multistep synthesis and the practical limits (ca. 65%) to primary amine selectivity and yield.
