Alumina containing about 2.2% by weight of Na+ has been found to be an effective catalyst for the vapor phase reduction of carbonyl compounds by alcohols and for the reverse reaction, the oxidation of the alcohols by carbonyl compounds. The reduction of a number of aliphatic and aromatic aldehydes and ketones by isopropyl alcohol and the oxidation of a number of primary and secondary alcohols by ketones like acetone and cyclohexanone are reported.

Enantioselective Addition

Different types of chiral "privileged" ligands 1 and 2 in promoting enantioselective addition of allylating agents to aliphatic and aromatic aldehydes are described. Here, a new concept in the asymmetric allylation reaction is presented. Redox [Cr (Salen) ] mediated addition of allyl halides to carbonyl compounds is described, and mechanistic investigations are discussed. These results open access to the fascinating area of the catalytic redox processes mediated by metallo-Salen complexes.
