Chloromethyl methyl ether-stannic chloride treatments of toluene, ethylbenzene, isopropylbenzene and tert-butyl benzene afforded respectively, 26.5, 16.8, 5.5 and 2.5percent orthoproducts.No meta-products could be detected (less than 0.5percent).Similar chloroalkylation of linear polystyrenes followed by conversion of the chloromethyl groups to hydroxylmethyl, yielded products possessing 5.0 +/- .3percent ortho-substitution.
