ABSTRACT:
For the preparation of methallylbenzene (.alpha.-olefin) and isobutenylbenzene (.beta.-olefin), and their p-substituted alkyl derivatives of Formulae 1 and 2, respectively, thermal cracking of neophyl chloride and the corresponding p-substituted neophyl chlorides of Formula 3 is performed, in the presence of an inhibitor for radical polymerization, with the resultant cracked product olefins of Formula 2 then isomerized to the corresponding .alpha.-olefin of Formula 1 by a further distillation in the presence of a mixture containing a basic compound and a polar solvent. ##STR1##
