Reaction Steps

7.6 g of 2-chloro-4,6-dimethylphenylmalonic acid according to Example (XXXV-1) were suspended in 22 ml of toluene and treated dropwise with 19.5 ml of thionyl chloride. The mixture was heated at 95° C. for 9.5 h, cooled and freed from the volatile constituents by passing argon through. The residues of thionyl chloride and the solvent were distilled off at 45° C. in a high vacuum. 6.6 g of 2-chloro-4,6-dimethylphenylchlorocarbonylketene were obtained as an oil which was slightly contaminated with 2-chloro-4,6-dimethylphenylacetyl chloride.
