ABSTRACT:
An unsaturated alicyclic carbinol or dicarbinol, e.g., 4-cyclohexene methanol or 4-cyclohexene-1,2-dimethanol, is obtained by subjecting a diolefin oxidation product, i.e., a polymeric peroxide, e.g., 1,3-butadiene polyperoxide, to Oxo reaction conditions, including an elevated temperature of the order of about 100.degree. to about 200.degree. C and carbon monoxide and hydrogen under elevated pressure in presence of a metal carbonyl catalyst, subjecting reaction mixture thus obtained to known hydrogenation or reducing conditions to convert carbonylic groups to hydroxyl groups employing a catalyst and hydrogen or a reducing agent, e.g., LiAlH.sub.4, the conditions being selective to preserve the unsaturated linkage desired in the product.
