copper mediated cross coupling cyclization oxidation a One Pot Reaction to construct polysubstituted pyrroles
ChemInform, 2014Co-Authors: Hengshan Wang, Hong Liang, Zhenfeng ChenAbstract:A novel copper-catalyzed One-Pot synthesis of polysubstituted pyrroles is described and a Reaction mechanism is also proposed.

copper mediated cross coupling cyclization oxidation a One Pot Reaction to construct polysubstituted pyrroles
Chemical Communications, 2014Co-Authors: Hengshan Wang, Hong Liang, Zhenfeng ChenAbstract:A novel and efficient procedure for the synthesis of polysubstituted pyrroles has been developed in this work. The polysubsituted pyrroles were synthesized directly from terminal alkenes, amines and β-keto esters through cross-coupling–cyclization–oxidation in the presence of a catalytic amount of cuprous chloride. This method provides a One-Pot synthesis route from terminal alkenes to polysubstituted pyrroles for the first time and opens a new area in cuprous catalysis.

palladium nanoparticles encapsulated in the mil 101 catalyzed One Pot Reaction of alcohol oxidation and aldimine condensation
Inorganic Chemistry, 2018Co-Authors: Yuyang Zhang, Linlin Ding, Lin Liu, Shiming Wang, Zhengbo HanAbstract:A bifunctional catalyst, Pd nanoparticles (NPs) encapsulated in MIL-101, has been synthesized by capillary impregnation. The as-prepared Pd@MIL-101 was characterized by powder X-ray diffraction, N2 physisorption, X-ray photoelectron spectroscopy, transmission electron microscopy, and high-angle annular dark field scanning transmission electron microscopy, indicating that Pd NPs were highly dispersed in the pores of MIL-101 without deposition of the nanoparticles on the external surface or aggregation. The bifunctional catalyst of Pd@MIL-101 exhibited highly catalytic activity for alcohol oxidation and aldimine condensation One-Pot Reactions, where Pd NPs affords good oxidation activity and MIL-101 offers Lewis acidity. In particular, Pd@MIL-101 yielded an effective catalytic performance with toluene as the solvent, K2CO3 as the co-catalyst, and 353 K as the optimum Reaction temperature for the One-Pot Reaction. After five cycles of reuse, Pd@MIL-101 still shows high catalytic performance. Above all, it is found that the enhanced catalytic performance was achieved via the synergistic cooperation of MIL-101 and Pd NPs.
