Process for the produciton of 2-chloroacetoacetic acid amides

Process for the production of 2-chloroacetoacetic acid amides. Diketene is converted at a temperature of +30° to -40° C. with the help of hydrogen chloride into acetoacetic acid chloride. Chlorine is introduced into the mixture at a temperature of +30° to -40° C., whereby 2-chloroacetoacetic acid chloride is formed. The latter is converted into the corresponding amide at a temperature of +50° to -40° C. by reaction with a N-compound having the formula: STR1 wherein (i) R=R'=H, or (ii) R=R'=alkyl, substituted alkyl, aryl, substituted aryl, alkyl aryl, substituted alkyl aryl, alkoxy aryl, substituted alkoxy aryl, alkoxy alkyl or substituted alkoxy alky, or (iii) R=H, and R'=alkyl, substituted alkyl, aryl, substituted aryl, alkyl aryl, substituted alkyl aryl, alkoxy aryl, substituted alkoxy aryl, alkoxy alkyl or substituted alkoxy alkyl.
