Palladium-Catalyzed Desulfitative Mizoroki-Heck Coupling Reactions of Sulfonyl Chlorides with Olefins in a Nitrile-functionalized Ionic Liquid

Paul Joseph Dyson, Pierre Vogel, Zhaofu Fei, Dongbin Zhao

Aryl and alkenyl sulfonyl chlorides can be used in Heck-Mizoroki-type couplings with mono- and disubstituted olefins in a nitrile-functionalized ionic liquid, viz. [C3CNpy][Tf2N]. Advantages over previously reported methods include: (1) use of a cheap cat ...

Catalytic hydrogenation of alkenes under biphasic conditions : understanding solvent effects

Corinne Daguenet

Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...

Structure of nitrile-functionalized alkyltrifluoroborate salts

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Dongbin Zhao

Two nitrile-functionalized alkyltriflouroborate anion based complexes [(Ph3P)(2)N][CH3CH(BF3)CH2CN] and [K(18-crown-6)][CH3CH(BF3)CH2CN] were synthesized and characterized by spectroscopic methods and single X-ray diffraction analysis. In the former comple ...

Hydrogenation and hydroformylation in ionic liquids, water and biphasic systems

Christian Ohlin

This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
