THE DIRECT SYNTHESIS OF α,β-UNSATURATED CARBONYL COMPOUNDS BY Pd(II) PROMOTED DEHYDROGENATION OF ALDEHYDES AND KETONES

Article abstract of DOI:10.1246/cl.1983.1207

α,β-Unsaturated aldehydes are prepared by the direct dehydrogenation of the corresponding saturated aldehydes by the coupled use of PdCl2(PhCN)2-AgOSO2CF3 in the presence of N-methyl-morpholine in good yields. α,β-Unsaturated ketones are also prepared via the Sn(II) enolate by a one-pot procedure from the corresponding saturated ketones.
