ABSTRACT OF THE DISCLOSURE The invention relates to a process for the production of optionally substituted aryl pyruvic acids by reacting option- ally substituted aryl methyl halides with carbon monoxide and a mixture of alcohol and water in the presence of a cobalt carbonyl and a basic compound. The process of the invention is characterised in that the reaction is carried out at a temperature in the range from -10 to +70°C in the presence of an alcohol and an alkali hydroxide as the basic compound. m e aryl pyruvic acids obtained by -the process according to the invention are important starting materials for the produc- tion of .alpha.-amino acids.
