Polyimidazolium Salts: Robust Catalysts for the Cycloaddition of Carbon Dioxide into Carbonates in Solvent-Free Conditions

Paul Joseph Dyson, Zhaofu Fei, Felix Daniel Bobbink, Wei Zhong

There is a growing interest in sustainable heterogeneous catalysts based on organic polymers. Here, we describe a series of polyimidazolium salt catalysts, prepared from the direct reaction of arene- bridged bis- and tris-alkyl halides with trimethylsilyli ...

A Structure-Activity Study of Nickel NNN Pincer Complexes for Alkyl-Alkyl Kumada and Suzuki-Miyaura Coupling Reactions

Rosario Scopelliti, Xile Hu, Marko Stojanovic, Thomas Clément Di Franco, Sébastien Carlos Keller

A new series of Ni NNN pincer complexes were synthesized and characterized. The main difference among these complexes is the substituents on the side arm amino group(s). No major structural difference was found except for the C-N-C angle of the various sub ...

Amine synthesis via iron-catalysed reductive coupling of nitroarenes with alkyl halides

Xile Hu, Chi Wai Cheung

(Hetero)Aryl amines, an important class of organic molecules in medicinal chemistry, are most commonly synthesized from anilines, which are in turn synthesized by hydrogenation of nitroarenes. Amine synthesis directly from nitroarenes is attractive due to ...

Synthesis of cyclic carbonates from diols and CO2 catalyzed by carbenes

Paul Joseph Dyson, Felix Daniel Bobbink, Martin Hulla, Shoubhik Das, Weronika Gruszka

The synthesis of cyclic carbonates from epoxides and CO2 is a well-established reaction, whereas the synthesis of cyclic carbonates from diols and CO2 is considerably more challenging, and few efficient catalysts are available. Here, we describe heterocycl ...

A rational synthesis of hierarchically porous, N-doped carbon from Mg-based MOFs: understanding the link between nitrogen content and oxygen reduction electrocatalysis

Ning Yan, Pierre Mettraux

Controlled mixtures of novel Mg-based metal-organic frameworks (MOFs) were prepared, with H+ or K+ as counterions. A linear relation was found between synthesis pH and K/H ratio in the resultant mixture, establishing the tunability of the synthesis. Upon p ...

A Computational and Experimental Study of Thieno[3,4-b]thiophene as a Proaromatic pi-Bridge in Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Fabrizio Giordano

Four D-pi-A dyes (D=donor, A=accpetor) based on a 3,4-thienothiophene pi-bridge were synthesized for use in dye-sensitized solar cells (DSCs). The proaromatic building block 3,4-thienothiophene is incorporated to stabilize dye excited-state oxidation poten ...

Nickel-Catalyzed Direct Alkylation of Terminal Alkynes at Room Temperature: A Hemilabile Pincer Ligand Enhances Catalytic Activity

Rosario Scopelliti, Xile Hu, Peng Ren, Pablo Marcelo Perez Garcia

Direct coupling of alkyl halides with terminal alkynes provides an efficient and streamlined access to alkyl-substituted alkynes, which are important synthetic intermediates, biologically active molecules, and organic materials. However, until now,there ha ...

Sulfonamide and Tertiary Amine as Nucleophiles in Pd(II)-Catalyzed Diamination of Alkynes: Synthesis of Tetracyclic Indolobenzothiazine S,S‑Dioxides

Qian Wang, Jieping Zhu, Bo Yao, Minh Tu Ha

Pd(II)-catalyzed oxidative double cyclization of the 1,2-diarylethynes bearing an N-methyl-N-(2-methoxycarbonyl)ethylamino and an aminosulfonyl group afforded indolobenzothiazine S,S-dioxides in good to excellent yields. The 2-(methoxycarbonyl)ethyl group ...

Synthesis of E-Alkyl Alkenes from Terminal Alkynes via Ni-Catalyzed Cross-Coupling of Alkyl Halides with B-Alkenyl-9-borabicyclo[3.3.1]nonanes

Xile Hu, Thomas Clément Di Franco, Alexandre Epenoy

The first Ni-catalyzed Suzuki-Miyaura coupling of alkyl halides with alkenyl-(9-BBN) reagents is reported. Both primary and secondary alkyl halides including alkyl chlorides can be coupled. The coupling method can be combined with hydroboration of terminal ...
