Aryl iodides and 2-(trifluoromethyl)acrylic acid reacted together in ligand-free Mizoroki-Heck reaction furnishing a quick and efficient access to highly valuable α-trifluoromethylacrylic acids. The useful transformation was independent with regard to the electronic nature of the aryl group substituent. A three-component one-pot version was also developed to give diverse substituted acrylates. The versatility of α-trifluoromethylacrylic acids was demonstrated by quick access to 3-CF3-coumarins as well as fluorinated analogues of therapeutic or cosmetic agents. Finally, we proposed a catalytic cycle based on the silver carboxylate salt, identified as a key intermediate in the reaction. (Figure presented.).

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

An efficient strategy for a high-yielding and stereoselective synthesis of α-trifluoromethyl unsaturated carboxylic acids directly from the reactions of 3,3,3-trifluoropropanoic acid (CF3CH2COOH) with various aryl aldehydes in the pr
