, (2008/06/13)
The present invention relates to a process for preparing 1-indanones of formula I: and isomers thereof, wherein R1, R2, R3, R4, R5, and R6 independently represent H or a C1-C20 hydrocarbon group or R1 and R2 or R2 and R3 or R3 and R4 and/or R5 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 hetero atoms, said ring optionally being substituted with a C1-C4 hydrocarbon group, said process comprising reacting a compound of formula II: wherein R1, 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.
