Hydrogenation of sorbic acid in ethyl acetate with [RhCl(PPh 3)3] was studied and compared to the hydrogenation of its K-salt in water catalyzed by [RhCl(mtppms)3]. Aqueous biphasic hydrogenation of sorbic acid with [RhCl(mtppms)3] as catalyst proceeded faster and more selectively than that in homogeneous solutions and afforded trans-hex-2-enoic acid with 80% selectivity.
