A novel 1-glycyl-3-methyl imidazolium chloride-palladium (II) complex [[Gmim]Cl-Pd (II)] was found to be a heterogeneous catalyst for an efficient Heck reaction with good to excellent yield under solvent free condition. Tetra-coordinated palladium complex was prepared by reacting PdCl 2 with 1-glycyl-3-methyl imidazolium chloride and its catalytic function invented for the CC bond formation. Spectroscopic evidence of complex has been proved by powder XRD, SEM, FT-IR and AFM. This protocol provides a simple strategy for the generation of a variety of new CC bonds under environmentally benign condition. © 2012 Elsevier B.V. All rights reserved.

Polymer-supported benzimidazolium based ionic liquid: an efficient and reusable Brønsted acid catalyst for Biginelli reaction

A novel, effective asymmetric 1-glycyl-3-methyl imidazolium chloride-iron(III) [[Gmim]Cl-Fe(III)] complex was synthesized and studied as organocatalyst in asymmetric aldol addition under solvent free condition at 25 C. The hydrophobic group of amino acid favors reagent diffusion toward the chloroglycine moiety increasing the catalytic activity of supported iron complex. This method contains simplified product isolation and catalyst recycling, affording substituted aromatic aldehydes imparting high yield of aldol with excellent stereo-selectivity. This recyclable heterogeneous catalyst provides a simple strategy for the generation of a variety of new CC bonds under environmentally benign condition. © 2013 Elsevier B.V.

Development of highly enantioselective asymmetric aldol reaction catalyzed by 1-glycyl-3-methyl imidazolium chloride–iron(III) complex

A novel, effective asymmetric 1-glycyl-3-methyl imidazolium chloride-copper(II) complex [[Gmim]Cl-Cu(II)] was synthesized and studied as organocatalyst for enantioselective Biginelli reaction under solvent free condition at 25°C. The hydrophobic group on amino acid favors reagent diffusion towards the chloroglycine moiety increasing the catalytic activity of supported palladium complex. Spectroscopic evidence of complex has been proved by Powder XRD, SEM, FT-IR and AFM. This method contains simplified product isolation and catalyst recycling, affording substituted aldehydes imparting high yield with excellent stereoselectivity. This recyclable heterogeneous catalyst provides a simple strategy for the generation of a variety of new C-C bonds under environmentally benign condition. © 2012 Elsevier B.V. All rights reserved.

Development and efficient 1-glycyl-3-methyl imidazolium chloride–copper(II) complex catalyzed highly enantioselective synthesis of 3, 4-dihydropyrimidin-2(1H)-ones

1-Glycyl-3-methyl imidazolium chloride-iron (III) complex [[Gmim]Cl-Fe(III)] was found to be a heterogeneous catalyst for an efficient and greener solvent free synthesis of esters by the condensation of carboxylic acids and alcohols with excellent yield at ambient temperature. This operation formulates very interesting, ecological perspective due to simple reaction condition, isolation, and purification of products. In addition, this method features reusability of catalyst, reduced waste, thus making new protocol more environmentally suitable whilst no catalyst leaching was observed. © Iranian Chemical Society 2012.

Novel and efficient method for esterification catalyzed by 1-glycyl-3-methyl imidazolium chloride-iron (III) complex

A novel, effective 1-glycyl-3-methyl imidazolium chloride-palladium(II) complex ([Gmim]Cl-Pd(II)) was synthesized and studied as an organocatalyst for the Sonogashira coupling reaction under solvent-free conditions at 25 °C. The hydrophobic group on amino acid favors reagent diffusion toward the chloroglycine moiety, increasing the catalytic activity of supported palladium complex. By this protocol, different aryl halides (Cl, Br and I) were reacted with phenylacetylene in good to excellent yields with turnover number 8.0 × 10 2 to 9.6 × 10 2. The catalyst was recycled for the reaction of bromobenzene with phenylacetylene for eight runs without appreciable loss of its catalytic activity and negligible metal leaching.
