1,1,3,3-substituted hydroxyindanes of the formula <IMAGE> wherein R1 is selected from the group of hydrogen, halogen and optionally substituted alkyl, cycloalkyl, aralkyl and aryl and the group <IMAGE> wherein X is sulphur or the group <IMAGE> R2 and R3 can be the same or different and are selected from the group of hydrogen, halogen and optionally substituted alkyl, cycloalkyl, aralkyl and aryl group, or, if R2 and R3 are in the ortho position to each other, they may form a condensed carbocyclic 5-membered ring together with the carbon atoms of the benzene ring to which they are attached as substituents, R4, R5, R6, R7, R8 and R9 are the same or different and are selected from the group of optionally substituted alkyl, cycloalkyl, aralkyl and aryl or R4 and R5 and/or R6 and R7 and/or R8 and R9 can form a cycloaliphatic ring together with the carbon atom to which they are attached as substituents or R6 and/or R7 can also be hydrogen and R10 and R11 can be identical or different and are selected from the group of hydrogen and optionally substituted alkyl or R10 and R11 can form a cycloaliphatic ring together with the carbon atom to which they are attached as substituents. The foregoing compounds are prepared by reacting an alkyl phenol in the presence of an acid catalyst at temperatures of from 100 DEG -350 DEG C. with an olefine.
