Beschreibung
Zusammenfassung:	A method for racemization of optically active 2,2-dimethyl-3-(1'-alkenyl)-cyclopropane-1-carboxylic acids of the formula: CH3CH3 ANGLE C ANGLE 2 R1 31 ANGLE C=CH-CH---CH-COOH ** R2 wherein R1 and R2 are each a hydrogen atom or an alkyl group having 1 to 4 carbon atoms or, when taken together with the carbon atom to which they are attached, represent a cycloalkylidene group having 4 to 6 carbon atoms, which comprises the step of contacting the corresponding acid halide with a Lewis acid.
