A general and highly chemo-, regio-, and stereoselective synthesis of α,β-unsaturated aldehydes by a domino hydroformylation/aldol condensation reaction has been developed. A variety of olefins and aromatic aldehydes were efficiently converted into various substituted α,β-unsaturated aldehydes in good to excellent yields in the presence of a rhodium phosphine/acid-base catalyst system. In view of the easy availability of the substrates, the high atom-efficiency, the excellent selectivity, and the mild conditions, this method is expected to complement current methodologies for the preparation of α,β-unsaturated aldehydes.

The invention concerns a process for the catalytic production of unsaturated aldehydes by reacting an olefin in the presence of carbon monoxide and hydrogen, a rhodium compound and organic phosphorus-containing ligands in an organic solvent as well as a co-catalyst formed from a weak organic acid and an organic amine.

Reduction of α-chloroalkyl phenyl (or methyl) sulfides with chromium(II) chloride in THF proceeds smoothly in the presence of LiI.The resulting (α-thioalkyl)chromium reagents add to aldehydes in a chemo- and stereoselective manner.
