Abstract

A process for the preparation of indane compounds of the formula ** (See formula) ** wherein R1 is hydrogen or an alkyl radical having 1 to 3 carbon atoms, provided that at least one of the symbols R1 is hydrogen; and R2 is hydrogen, an alkyl radical having 1 to 6 carbon atoms, an acyl radical or a cycloalkyl radical, provided that at least one of the symbols R2 which is hydrogen is 1, and provided that carbons 1 and 3 are both quaternary, carbons 4 and 7 are both devoid of acyl groups, characterized in that it consists in reacting a compound of the formula ** (See formula) ** wherein R1 has the same meaning as stated above and R3 is hydrogen, an alkyl radical having 1 to 6 carbon atoms or a cycloalkyl radical, provided that at least one of the symbols R3 must be hydrogen and also that if carbons 1 and 3 are both quaternary, at least one of the symbols R3 attached to carbons 5 and 6 must be hydrogen, with an acylating agent, in the presence of a Lewis acid.
