Process for preparing an olefinic product comprising partially hydrogenated β-farnesene in two stages. In the first stage, reaction conditions are controlled to favor the hydrogenation of β-farnesene over auto dimerization and polymerization of β-farnesene. In the second stage, reaction conditions are controlled to favor the hydrogenation of dihydro-β-farnesene and tetrahydro-β-farnesene to form hexahydro-β-hydrofarnesene over the hydrogenation of hexahydro-β-hydrofarnesene to form farnesane.

Methods for preparing isotopically modified 1,4-diene systems from non-isotopically modified 1,4-dienes involve selective oxidation of one or more bis-allylic position(s), or the preparation of isotopically modified 1,4-diene systems via trapping pi-allylic complexes with a source of deuterium or tritium. Such methods are useful for preparing isotopically modified polyunsaturated lipid including polyunsaturated fatty acids and polyunsaturated fatty acid derivatives.
