A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an &#x3b1;,&#x3b2;-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is &#x3b1;,&#x3b2;-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C-C) feedstocks instead of hydrogen (H).

Transfer-hydrogenation process

This invention pertains to hydroformylation catalysts containing a mixture of isomeric forms of halo-phosphorus ligands. This invention also describes a procedure for preparing isomers of certain halophosphite ligands, which contain the phosphorus atom in a macrocyclic ring.
