The rhenium hetaphydride complex was found to be a versatile, homogeneous catalyst for dehydrogenative functionalization of alcohol. The dehydrogenative C-C coupling of alcohols and carbonyl compounds was carried out in the absence Of base and hydrogen acceptors to afford a series of alpha,beta-unsaturated carbonyl compounds. A possible dual activation pathway was proposed by mechanistic investigations.
The Employment of Sodium Hydride as a Michael Donor in Palladium‐catalyzed Reductions of α, β‐Unsaturated Carbonyl Compounds
Sodium hydride was employed as a Michael donor under the catalysis of PdCl2 for 1,4‐conjugate reductions of α, β‐unsaturatedcarbonylcompounds, which features operational simplicity, mild conditions and high atom‐economy. The merits of NaH as a reductant were demonstrated by the one‐pot or cascade reactions for the syntheses of complex molecules.
