- High catalytic activity of as-synthesized, ordered porous silicate-quaternary ammonium composite for Knoevenagel condensation
-
The Knoevenagel condensation of carbonyl compounds with active methylene compounds catalyzed by as-synthesized, ordered porous silicate-quaternary ammonium composite materials gave corresponding α,β-unsaturated esters in high yields under very mild liquid phase conditions.

- Three-dimensional porous coordination polymer functionalized with amide groups based on tridentate ligand: Selective sorption and catalysis
-
To create a functionalized porous compound, amide group is used in porous framework to produce attractive interactions with guest molecules. To avoid hydrogen-bond formation between these amide groups our strategy was to build a three-dimensional (3D) coo

- Copper-catalyzed 1,4-addition of organoboronates to alkylidene cyanoacetates: Mechanistic insight and application to asymmetric catalysis
-
In addition: A copper/N-heterocyclic carbene(NHC)-catalyzed 1,4-addition of organoboronates to alkylidene cyanoacetates was developed, in which the catalytic cycle is proposed to consist of a transmetalation/insertion/ligand exchange. An effective asymmetric variant has also been achieved by the use of a chiral NHC ligand (see scheme). Copyright
