The rhodium-catalyzedhydroformylation-hydrogenation of 1,2-allenyl-phosphineoxides and -phosphonates is reported in this paper. The regioselectivity was well controlled, affording only saturated linear γ-phosphinyl aldehydes under the standard conditions: (carbonyl)tris(triphenylphosphine)-rhodium hydride [RhH(CO)(PPh3)3] (3 mol%), triphenylphosphine (PPh3) (10 mol%), carbon monoxide (CO) (2.4×106 Pa)
