organic–inorganic hybridcatalyst was prepared by immobilizing 3-methylaminopropyl moiety onto mesoporous silica, MCM-41, and applied for solidbasecatalyst of three-component one-pot reaction, i.e. Knoevenagel condensation of aldehyde with the active methylene compound to yield an electron deficient alkene which is subjective to be reacted with nitromethane by Michaeladdition to form tri-substituted
Visible light-mediated oxidative decarboxylation of arylacetic acids into benzyl radicals: addition to electron-deficient alkenes by using photoredox catalysts
arylacetic acids bearing an amino group at the para-position in the benzene ring with alkenes in the presence of a catalytic amount of transition metal polypyridyl complexes as photocatalysts under visible light illumination proceed smoothly to give the corresponding benzylated products via oxidative decarboxylation in good to high yields.

The conjugate hydrocyanation of α-cyanoacrylates through chemoselective 1,4-addition to synthesise α,β-dicyanopropanoates by one-pot two-step procedure usingpotassiumhexacyanoferrate(II) as an eco-friendlycyanidesource, benzoyl chloride as a promoter and potassium carbonate as a catalyst is described. The advantages of this protocol are use of a non-toxic, non-volatile and inexpensive cyanating reagent
An asymmetric organocatalytic [4 + 2] cycloaddition between α-substituted allenoates and dual activatedolefins using bifunctional N-acyl aminophosphine catalysts is described. The use of 2-cyano acrylate derived olefins led to the first successful incorporation of an electrophile derived from an aliphatic aldehyde into this reaction.
