The pyrolysis of 2-aryl-1-benzyl-3,5-dimethyl(I)-, 5-chloro-3-methyl(II)-, 3-substituted-benzyl-5-methyl(III)- and 3-substituted-benzyl-5-chloro-(IV)-benzimidazolines has been carried out to study the orientation of their elimination reactions.The benzyl group is eliminated in preference to methyl in benzimidazolines of the types (I) and (II) irrespective of the nature of the substituent in phenylene and aryl moieties.The course of the elimination reaction in compounds of the types (III) and (IV) appears to be determined by the relative stabilities of benzyl and substituted benzyl radicals.The structures of the pyrolysis products have been established on the basis of spectral and chemical evidences.
