Study of Lewis acid accelerated palladium catalyzed CH activation
Acceleration of palladium catalyzed CH activation by various Lewis Acids was demonstrated on the directed ortho-alkenylation and acylation of acetanilide and urea derivatives. The universality of this effect was investigated by the study of different palladium catalysts, directing groups in the aromatic substrates and versatile Lewis acids. Experiments were carried out to monitor the reactions and to compare the behavior and activity of different types of Lewis acids. Kinetic investigation revealed a rate determining CH activation step, and DFT studies were performed for the explanation of Lewis acid effect on CH activation.
期刊介绍：
The Journal of Molecular Catalysis A: Chemical publishes original, rigorous, and scholarly full papers that examine the molecular and atomic aspects of catalytic activation and reaction mechanisms in homogeneous catalysis, heterogeneous catalysis (including supported organometallic catalysis), and computational catalysis.
