Magnetically recyclable Schiff-based palladium nanocatalyst [Fe3O4@SiNSB-Pd] and its catalytic applications in Heck reaction
Hafizi, Hamid; Rahman, Md. Lutfor; Sani Sarjadi, Mohd; Salim Akhter, Mohammed; Walker, Gavin M.; O’Reilly, Emmet J.; Collins, Maurice N.; Sarkar, Shaheen M. (Elsevier, 2022-04-18)Abstract A magnetically separable palladium nanocatalyst has been synthesized through the immobilization of palladium onto 3-aminopropylphenanthroline Schiff based functionalized silica coated superparamagnetic Fe3O4 ... -
Mesoporous Silica-Supported Sulfonyldiamine Ligand for Microwave-Assisted Transfer Hydrogenation
Sarkar, Shaheen M.; Ali, Md. Eaqub; Islam, Md. Shaharul; Rahman, Md. Lutfor; Rashid, S. S.; Karim, M. R.; Yusoff, Mashitah Mohd (Journal of Nanomaterials, 2015-07-01)-Sulfonyl-1,2-diamine ligands, derived from 1,2-diaminocyclohexane and 1,2-diaminopropane, were immobilized onto mesoporous SBA-15 silica. The SBA-15-supported sulfonyldiamine-Ru complex was prepared in situ under microwave ... -
Preparation of mesoporous SBA-16 silica-supported biscinchona alkaloid ligand for the asymmetric dihydroxylation of olefins
Sarkar, Shaheen Md; Ali, Md. Eaqub; Rahman, Md. Lutfor; Mohd Yusoff, Mashitah (Hindawi Publishing Corporation, 2014-06-15)Optically active cinchona alkaloid was anchored onto mesoporous SBA-16 silica and the as-prepared complex was used as a heterogeneous chiral ligand of osmium tetraoxide for the asymmetric dihydroxylation of olefins. The ... -

Preparation of Mesoporous Silica-Supported Chiral Amino Alcohols for the Enantioselective Addition of Diethylzinc to Aldehyde and Asymmetric Transfer Hydrogenation to Ketones
Sarkar, Shaheen M.; Ali, Md. Eaqub; Rahman, Md. Lutfor; Yusoff, Mashitah Mohd (Hindawi Publishing Corporation, 2015-08-26)Optically active (−)-ephedrine, (−)-ephedrine, and (−)-prolinol were immobilized onto cubic mesoporous MCM-48 silica. The immobilized amino alcohols served as a heterogeneous chiral catalyst for the asymmetric addition ... -
Silica-coated magnetic palladium nanocatalyst for Suzuki-Miyaura cross-coupling
Shaheen M., Sarkar; John J., Hannan; Mohammed Salim, Akhter; Sarjadi, Mohd Sani; Rahman, Md. Lutfor (Elsevier, 2022-05-23)A silica-coated magnetically separable Schiff-base palladium nanocatalyst was developed. Amorphous silica was used to encapsulate the magnetic Fe3O4 and an organic amine functionality was added to the silica surface. The ...
