An Efficient Synthesis of Annulated Novel Dihydropyridine Derivatives using Zeolite H-BEA and Zeolite BEA-SO3H
Abstract: Modified zeolite (zeolite BEA-SO3H) was synthesized with intent to improve the surface area and Si/Al ratio by loading chlorosulphonic acid onto zeolite H-BEA. Parent and modified zeolite were characterized by variety of characterization techniques such as, ICP, FT-IR, XRD, TGA, NH3-TPD,BET surface area, etc. The catalytic applications of parent and modified zeolite H-BEA were demonstrated through the synthesis of novel quinoline and benzoquinoline substituted dihydropyridines (DHPs) via one pot Hantzsch …

CuO/TiO2 Nanocomposites: Effect of Calcination on Photocatalytic Hydrogen Production
Abstract: Hydrothermally synthesized TiO2 nanorods were subjected to calcination from 350 to 550 °C and tested their catalytic performance for hydrogen (H2) production in aqueous glycerol solution under solar irradiation. High rate of H2 evolution ca.300 µmol.h−1.g−1cat was recorded with TiO2 nanorods calcined at 500 °C. The nanocomposites were prepared by varying Cu-loading 0.1 to 2.0 wt% and activated at 350 or 500 °C. About 25 folds enhancement in H2 production …

Catalytic Applications of Copper Species in Organic Transformations: A Review
Abstract: Copper a naturally occurring element is present in the earth's crust, in oceans, lakes, and rivers, from minute trace element levels through to rich mine deposits. It is essential to life – plants, fish, animals and humans all need copper to function properly. Homogeneous copper catalyzed reactions are widely used for the construction of important organic molecules, including pharmaceuticals, commodity chemicals, and polymers. The development of copper catalysis has been …

Diaminoglyoxime Palladium (II) Chloride As An Efficient Catalyst for the Suzuki-Miyaura Cross-Coupling Reaction under Aerobic Conditions in H2O/EtOH Solution
Abstract: The preparation of diaminoglyoxime palladium (II) chloride (PdCl2/DAG complex) and the use of this catalytic system in Suzuki-Miyaura cross-coupling reactions under aerobic and phosphine-free conditions in aqueous solutions is studied. Aryl halides, coupled with phenylboronic acids smoothly afford the corresponding cross-coupling products with excellent yields (80–98%). The catalytic system showed excellent performance for the Suzuki-Miyaura cross-coupling reaction of less reactive aryl chlorides with aryl boronic acids. The reaction conditions have …
