Abstract
A novel efficient and eco‐friendly nanocrystalline ZnO catalyst was used for the Knoevenagel condensation and for the reduction of CC double bonds at room temperature in the absence of solvents.

Indium hydride (Cl 2 InH) generated in situ from a combination of a catalytic amount of indium(III) chloride and sodium borohydride selectively reduces the carbon carbon double bond in conjugated alkenes such as a,a-dicyano olefins, a,b-unsaturated nitriles, cyano esters, cyanophosphonate, diesters

Conjugated double and triple bonds are reduced into alkenes using non-hazardous SmI 2 /H 2 O/amine mixtures as reducing agents in THF. Isolated alkenes are not reduced during these reductions. All the reactions studied are quantitative and are completed in less than five minutes.
