| abstract |
The invention relates to a novel method for producing α-arylmethyl-carbonyl compounds of formula (III), characterized in that aryl and heteroarylacetic acids and derivatives thereof of formula (I) having α-halogenmethyl-carbonyl compounds of formula (II) are converted in the presence of a palladium catalyst, a phosphine ligand, an inorganic base and a phase transfer catalyst, optionally using an organic solvent. |
