Nickel?alkyne?functionalized metal?organic frameworks: An efficient and reusable catalyst

Electron-donating groups in the robust MOF motif are able to provide an excellent catalytic platform, therefore obtaining site-isolated metal sites. In this study, the terminal alkyne is firstly introduced into UiO-66-type metal-organic frameworks (UiO-66-alkyne). Herein, to further study the application potential of this material, a covalently bonded nickel catalyst based on the alkynyl-tagged UiO-66-alkyne has been prepared and afforded us unprecedented highly dispersed and highly efficient catalytic active species. Meanwhile, this nickel-contained catalyst method for joining metals provided an alternative pathway regarding catalyst designing. With UiO-66-alkyne-Ni, the heterogeneous transformation of homogeneous catalysts is realized. Using benzaldehyde and malononitrile as starting materials, we were able to catalyze the Knoevenagel condensation within 45 min under room temperature with yield (> 99 %). Moreover, the recovery rate of the UiO-66-alkyne-Ni also outperformed previous MOFs in both small-scale and gram-level reactions, which shows UiO-66-alkyne-Ni is a potential contributor to the subsequent industrialization.

The Knoevenagel condensation using quinine as an organocatalyst under solvent-free conditions

The Knoevenagel condensation between active methylene compounds and aromatic carobonyl compounds has been developed using quinine as an organocatalyst to afford various electrophilic alkenes in excellent yields (up to 90%). In the presence of a catalytic amount of quinine (15 mol%), the reaction proceeded at room temperature (RT) under solvent-free conditions. In this green approach, the organocatalyst was recovered and recycled for up to four cycles without appreciable loss of activity.

An efficient and recyclable acid-base bifunctional core-shell nano-catalyst for the one-pot deacetalization-Knoevenagel tandem reaction

A novel magnetic nanoparticle supported acid-base bifunctional catalyst was synthesized by anchoring [3-(2-aminoethyl)aminopropyl]triethoxysilane and sulfonic acid successively onto the surface of silica-coated Fe3O4 nanoparticles. The as-prepared nanoparticle catalyst was used as a quasi-homogeneous and recyclable catalyst for the one-pot deacetalization-Knoevenagel tandem reaction of benzaldehyde dimethylacetals and malononitrile. It showed high catalytic activity because the reaction proceeded smoothly and afforded benzylidenemalononitriles in excellent yields. Besides, it showed synergistic effect and facilitated the mass transfer process during the tandem reaction because the two catalytic moieties were connected together on the same MNP. Moreover, the catalyst can be readily recovered under an external magnetic field and reused without any significant loss of the catalytic activity after six runs.
