Disclosed in a process for the homogeneous, catalytic hydrogenation of epoxyalkenes and epoxycycloalkenes, especially conjugated .gamma.,.delta.- epoxyalkenes and .gamma.,.delta.-epoxycycloalkenes, to the corresponding expoxyalkanes and epoxycycloalkanes using a solution of a complex rhodium catalyst whereby the olefinic unsaturation is hydrogenated without significant hydrogenolysis of the conjugated epoxy group.

L'invention concerne un procédé d'hydrogénation catalytique homogène d'époxyalcènes et d'époxycycloalcènes, en particulier d'époxyalcènes .gamma.,.delta. et d'époxycycloalcènes .gamma.,.delta. conjugués pour obtenir les époxyalcanes et les époxycycloalcanes correspondants en utilisant une solution de catalyse aux complexes de rhodium, en vertue duquel l'insaturation oléfinique est hydrogénée sans hydrogénolyse significative du groupe époxy conjugué.
