Reactions of chlorine gas on six aromatic acetals, the benzaldehyde di-n-alkyl acetals, C6H4-CH(OR)2 where R=ethyl (1a), n-propyl (2a), n-butyl (3a), isobutyl (4a), n-amyl (5a) and isoamyl (6a) were studied. The products were analyzed by IR and 1H NMR spectroscopic techniques and were found to be ring chlorinated alkyl benzoates. A plausible mechanism has been proposed based on the experimental observations and the effect of the alkyl groups on the product yield.
