The present invention relates to a process for preparing 1-indanones of formula (I) and isomers thereof, wherein R?1, R2, R3, R4, R5, and R6¿ independently represent H or a C¿1?-C20 hydrocarbon group or R?1 and R2 or R2 and R3 or R3 and R4¿ and/or R?5 and R6¿ together with the carbon atoms to which they are attached form a saturated or unsaturated 5- or 6-membered ring, said hydrocarbon group and/or said ring optionally containing one or more hereto atoms, said ring optionally being substituted with a C¿1?-C4 hydrocarbon group, said process comprising reacting a compound of formula (II), wherein R?1, R2, R3, R4, R5, and R6¿ have the same meaning as defined above, with a chlorinating agent, followed by reaction with a Friedel-Crafts catalyst. The invention further relates to the preparation of the corresponding indenes.
