Abstract An environmentallyfriendly method for the construction of C(sp2)-CN bond on water has been described, and (Z)-2-(2-oxoindolin-3-ylidene)-2-arylacetonitriles were synthesized by using CeCl3· 7H2O as a catalyst. The reaction offers access to alkenyl nitriles in good-to-excellent yield. The investigations will be beneficial to reduce the use of toxic organic solvents and explore the efficient
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.
