Facile procedures for the synthesis of mono-, di- and triphenylindanee derivatives from the alcohols 1-4 are described thus treatment with 85% H(2)SO(4), AlCl(3)/CH(3)NO(2), H(3)PO(4) and/or PPA under varying conditions produced 1,1-dimethyl-3-phenylindanee 6 from 2-methyl-4,4-diphenyl-2- butanol 1, 3,3-dimethyl-1,1-diphenylindanee 9 from 2-methyl-4,4,4-triphenyl-2-butanol 2, 1-methyl- 1,3-diphenylindanee 12 from 2,4,4-triphenyl-2-butanol 3 and 1,1,3-triphenylindanee 15 from 1,1,3,3-tetraphenyl-1-propanol 4. The starting and final products were characterized by elemental, IR, (1)H NMR and MS analyses.
