A palladium-catalyzed carbonylative coupling of aryl iodides with a (trifluoromethyl)copper reagent has been developed. A wide range of substrates have been transformed into their corresponding trifluoromethyl ketones in good to excellent yields under mild conditions with high efficiency and excellent functional-group compatibility. Preliminary mechanistic investigations suggest that the transmetallation of an acylpalladium intermediate with the (trifluoromethyl)copper reagent seems to be involved in the catalytic cycle. Notably, this report represents one of the few studies on carbonylative coupling with organocopper reagents.
Catalytic asymmetric hydrogenation of α-CF3- or β-CF3-Substituted acrylic acids using Rhodium(I) complexes with a combination of chiral and achiral ligands

Only the mixture works! Acrylic acid derivatives with CF3 substituents in α or β position were efficiently hydrogenated in the presence of a RhI complex with a chiral secondary phosphine oxide (SPO; see scheme) and an achiral Ph3P as ligands. The corresponding propanoic acid derivatives were obtained with generally high conversion (>99 %) and high enantioselectivity (92->99 %). Copyright
