Irradiation of 1-naphthol (1a) and its 2-alkyl and 6-methoxy derivatives 1b-d with 5 equiv of AlCl3 or AlBr3 in CH2Cl2 gave (chloromethyl)indanones 4a-d in 41-72percent yields.Irradiation of 1a with AlBr3 in CH2Br2 afforded (bromomethyl)indanone 5a in 54percent. 3-Methylderivative 1e was unreactive and 4-methyl derivative 1f underwent isomerization to 1e.
