- Rh-Catalyzed Deformylative Coupling of Salicylaldehydes with Acrylates and Acrylamides
-
An unprecedented deformylative coupling of salicylaldehydes to acrylates and acrylamides under Rh-catalyzed conditions is reported. These deformylative couplings afforded o-hydroxycinnamates and o-hydroxycinnamamides with broad functional group tolerance and high chemoselectivity under milder reaction conditions.

- Unnatural Amino Acid Synthesis Enabled by the Regioselective Cobalt(III)-Catalyzed Intermolecular Carboamination of Alkenes
-
Herein, we report an unprecedented regioselective and entirely atom-economic cobalt(III)-catalyzed method for the non-annulative, intermolecular carboamination of alkenes. The methodology enables the direct synthesis of unnatural amino acid derivatives an

- Ligand-free copper-catalyzed arylation of olefins by the mizoroki-heck reaction
-
A novel ligand-free copper-catalyzed Mizoroki-Heck cross-coupling reaction of various aryl iodides with olefins has been developed. Both the solvent and the base were found to have a fundamental influence on the efficiency of the transformation in the presence of 10 mol% Cu, with DMF and tetramethylammonium bromide (TMAB) being the optimal solvent and base, respectively. As a result, a set of the corresponding E-internal olefins were obtained selectively in moderate to good yields.

- Highly efficient, recyclable Pd(II) catalysts with bisimidazole ligands for the heck reaction in ionic liquids
-
(Matrix presented) New Pd(II) complexes with bisimidazole ligands were prepared and proved to be effective catalysts for the Heck reaction under phosphine-free conditions using ionic liquids as solvents. This system could be recycled five times without any loss of catalytic activity.
