  • Patent number: 4847229
    Abstract: The invention is a process for the hydroformylation of C.sub.2-4 alkenes, formyl-substituted C.sub.2-4 alkenes, aryl-substituted alkenes, unsaturated norbornane ring-containing compounds, and .alpha.-unsaturated acetals which comprises contacting a C.sub.2-4 alkene, a formyl-substituted C.sub.2-4 alkene, aryl-substituted alkene, an unsaturated norbornane ring-containing compound or an .alpha.-unsaturated acetal in a polar organic solvent with water and carbon monoxide in the presence of a catalytic amount of a catalyst which comprises a mixture of (a) an alkali metal iron carbonyl or alkaline earth metal iron carbonyl which corresponds to the formula M.sub.a Fe.sub.x (CO).sub.y and (b) iron pentacarbonyl under conditions such that an alcohol or aldehyde derivative of a C.sub.2-4 alkene, a formyl-substituted C.sub.2-4 alkene, an aryl-substituted alkene, unsaturated norbornane ring-containing compound or an .alpha.
