Synthesis of BaMoO₄ Nanocrystallites Using Sol-Gel Process

Abstract

BaMoO4nanocrystallites were synthesized successfully using Sol-gel process with (NH4)6Mo7O24•4H2O, BaCl2•2H2O, citric acid and PEG400 as original materials. The result shows that well-crystallized BaMoO4nanoparticles were formed at 600°C with size of ca.50nm. The synthesized BaMoO4nanocrystallites were characterized by XRD and IR, and the optical property was studied as well.

Highly efficient amine‐based catalytic system for room temperature Suzuki–Miyaura reactions of aryl halides with arylboronic acids

“…Ligand‐promoted palladium catalyzed Suzuki–Miyaura cross‐coupling reactions have proven to be one of the most powerful strategies for synthesizing diversified biaryls, which constitute an important class of compounds for the pharmaceutical as well as agrochemical industries 1–6. Among different ligands, noticeable advances have been achieved with phosphine‐based ligands (such as simple tertiaryphosphines,1, 2, 7, 8 hemilabile‐type phosphines,2, 9–13 sterically crowded biphenyl‐type phosphines14, 15 and other electron‐rich phosphines16–18) and with other ligands that are capable of forming palladacycles (e.g.…”
