Manganese-mediated reductive amidation of esters with nitroarenes

Xile Hu, Peng Wang, Chi Wai Cheung, Ning Shen

Amides are ubiquitous molecules in nature and in synthetic chemistry. Here we report a convenient and efficient method to synthesize N-aryl amides via amidation of esters with nitroarenes. In the presence of manganese metal, this amidation proceeded smooth ...

Au Core-Pd Shell Bimetallic Nanoparticles Immobilized within Hyper-Cross-Linked Polystyrene for Mechanistic Study of Suzuki Cross-Coupling: Homogeneous or Heterogeneous Catalysis?

Lioubov Kiwi

The synthesis of catalytically active bimetallic Au-Pd nanoparticles stabilized in hyper-cross-linked polystyrene (HPS) for Suzuki cross-coupling of 4-bromoanisole (4-BrAn) and phenylboronic acid is presented. The core-shell structure with a thin (less tha ...

A Generalized Picture of C-C Cross-Coupling

Matthew Wodrich, Michael Markus Busch

Transition metal catalyzed cross-coupling reactions occupy a privileged position in chemistry because of their ability to link myriad functional groups. The numerous variants of this reaction types (e.g., Suzuki, Kumada, Negishi, etc.) differ in the transm ...

Synthesis of Alkynylated Heterocycles by Direct C-H Alkynylation or Domino Alkynylation Reactions

Yifan Li

Heterocycles are important compounds in organic chemistry. To introduce functional groups on heterocycles or synthesize functionalized heterocycles stays a hot topic of research. Among all the functional groups, alkynes attracted a lot of attention not onl ...

Catalysts of Suzuki Cross-Coupling Based on Functionalized Hyper-cross-linked Polystyrene: Influence of Precursor Nature

Lioubov Kiwi

This paper describes synthesis of Pd-containing catalysts of Suzuki cross-coupling based on amino-functionalized hyper-cross-linked polystyrene at variation of Pd precursor nature (PdCl2, PdCl2(CH3CN)(2), or PdCl2(PhCN)(2)). The investigation of the influe ...

Linear Scaling Relationships and Volcano Plots in Homogeneous Catalysis – Revisiting the Suzuki Reaction

Matthew Wodrich, Michael Markus Busch

Linear free energy scaling relationships and volcano plots are common tools used to identify potential heterogeneous catalysts for myriad applications. Despite the striking simplicity and predictive power of volcano plots, they remain unknown in homogeneou ...
