1,1,3,3-SUBSTITUTED HYDROXY INDANES HAVING THE FORMULA STR1 wherein R1, R2 and R3, which may be the same or different, are selected from the group of hydrogen, halogen and optionally substituted alkyl, cycloalkyl, aralkyl and aryl, in addition to which R2 and R3, when they are in the ortho position relative to one another, may be taken together with the carbon atoms of the benzene ring to which they are attached to form a 5 membered carbocyclic ring, R4 is STR2 wherein R10 and R11, which may be the same or different, are selected from the group of hydrogen and optionally substituted alkyl, cycloalkyl, aralkyl and aryl, and R5, r6, r7, r8 and R9, which may be the same or different, are selected from the group of optionally substituted alkyl, cycloalkyl, aralkyl and aryl, the arrangement being such that R5 and R10 and/or R6 and R7 and/or R8 and R9 may form together with the carbon atoms to which they are attached a cycloaliphatic ring in addition to which R6 and/or R7 may also represent hydrogen.
