Highly efficient recyclable heterogeneous palladium catalyst for C–C coupling, amination and cyanation reactions

Palladium catalysts supported on amine-functionalized glycidyl methacrylate gel type terpolymers. Synthesis, characteristics and study of catalytic activity in Suzuki–Miyaura reactions

“…Both the systems including Pd(0) nanoparticles [23][24][25][26][27] and those bearing Pd(II) complexes [28][29][30][31][32][33][34][35] were studied successfully as catalysts in Suzuki-Miyaura reactions. Such systems distinguish a low level of palladium losses.…”

N-functionalized L-proline anchored MCM-41: A novel organic–inorganic hybrid material for solvent-free aminolysis of styrene oxide under microwave irradiation

“…The synthesis of L-proline derivative (L-prol-N-pTMS) was carried out by a methodology inspired from Islam and co-workers for the synthesis of anthranilic acid-functionalized polystyrene resin. 29 In a typical experiment, L-proline (2.3 g, 20.0 mmol) and K 2 CO 3 (3.0 g, 21.7 mmol) were dissolved in 7 mL DMSO and vigorously stirred for 15 min at room temperature. The reaction mixture was irradiated four times (each time for 2 min with 1 min intervals) at 420 W in which the temperature raised to 180 °C to give a viscous liquid.…”

Fabrication of Pd Nanoparticles Embedded C@Fe3O4 Core–Shell Hybrid Nanospheres: An Efficient Catalyst for Cyanation in Aryl Halides

“…Since then a number of reports were available using this reagent in the presence of Pd catalysts such as Pd(OAc) 2 , 30-31 several Pd complexes [32][33][34][35][36][37][38][39][40][41][42][43][44][45] and Pd/C, [46][47] were developed. The serious drawbacks of these metal catalysts are metal contaminations in the final products, non-reusability and deactivation of the catalysts associated with the use of homogeneous system and hence are still unwelcoming.…”
