Boric Acid-Functionalized Fe3O4@SiO2 as a Novel Superparamagnetically Recoverable Nano Catalyst for Mukaiyama-Aldol Reaction
We have reported the fabrication of boric acid incorporated into surface of magnetite nanoparticles. The catalyst was characterized using spectroscopic, magnetic and thermal techniques (FT-IR, SEM, XRD, ICP, VSM and TGA). It catalyzed Mukaiyama aldol reaction of a ketene silyl acetal type nucleophile ((1-methoxy-2-methylprop-1-enyloxy) trimethylsilane), and various aldehydes (aromatic, aliphati...

متن کاملGold Functionalized Supported Ionic Liquids Catalyst for CO Oxidation
The present study tries to give an insight to the combination of the homogeneous and heterogeneous catalytic properties in a new class of materials. Well dispersed gold nanoparticles on an ionic liquid layer supported on a mineral carrier have been prepared. This work is concentrated on the characterizations and understanding of the interactions between all the components of the catalytic syste...
متن کاملAlkaline ionic liquids applied in supported ionic liquid catalyst for selective hydrogenation of citral to citronellal
The challenge in preparation of ionic liquids containing a strong alkaline anion is to identify a suitable cation which can tolerate the harsh conditions induced by the anion. In this study, a commercial quaternary ammonium compound (quat) benzalkonium [ADBA] (alkyldimethylbenzylammonium) was used as a cation in the synthesis of different alkaline ionic liquids. In fact, the precursor, benzalko...
متن کاملSynthesis of densely functionalized chromenes using a magnetic recoverable ionic liquid as the catalyst
In the present study, robust, versatile and straightforward strategy for the diversity-oriented convergent synthesis of a vast range of highly functionalized and biologically effective chromenes is introduced with the reaction of malononitrile, dimedone/cyclohexadione/4-hydroxycoumarin and benzaldehydes in the presence of [γ-Fe2O3@HAp-Si(CH2)3BF4@DMIM] as the catalyst. The structures of all the...
