A process for preparing N-acylglycine derivatives of general formula (III) is characterised in that a carboxylic acid amide of general formula (II) is carbonylated with an aldehyde of formula RCHO in the presence of a solvent and of a mixture comprising a palladium compound, an ionic halogenide and an acid which acts as a catalyst, at a temperature from 20-200 °C and under a CO-pressure from 1-150 bars. |
