Beschreibung
Zusammenfassung:	Carbonyl halides I I where R1 is H, alkyl, cycloalkyl, haloalkyl or halocycloalkyl, R2 and R3 are each alkyl, cycloalkyl, haloalkyl or halocycloalkyl and may furthermore be bonded to one another to form a 5-membered to 7-membered ring and is halogen, are prepared by reacting an alkyl halide II II with carbon monoxide under superatmospheric pressure in the presence of a catalytic amount of a) aluminum bromide and in the presence or absence of a solvent or b) aluminum chloride or bromide and in the presence of a halohydrocarbon and a carbonyl halide of the formula III R4-CH2-CO-Hal (III) where R4 is hydrogen or C1-C4-alkyl and Hal is halogen.
