Zeolites have been used to enhance the / r i-selectivity of chlorination reactions. For example, anisole has been chlorinated using sulfuryl chloride and ZF520 zeolite under reflux conditions [10]. A yield of 81% was achieved with a para to ortho product ratio of 74 26. Smith et al. reported complete conversion of alkylbenzenes using tertiary-butyl hypochlorite and HNaX zeolite at room temperature with para to ortho ratios of greater than 90 10 [11]. Molecular chlorine in the liquid phase with KL zeolite as the catalyst has been reported to give excellent para selectivity and good yields for deactivated benzenes [12].
