Abstract

The participation of ion-paired Lewis acid/Lewis base in the dehydrohalogenations of 1,2-dibromo-1,1-diarylalkanes catalyzed by Fe-0 and byFe(II) and Fe(III) bromides was investigated. The reactivities of thecatalyst employed were correlated with their chemical hardness. The influence of para substituents on the phenyl rings of the substrates and the results obtained in Lewis-acid-catalyzed and thermal dehydrobromination of the same compounds were compared. The experimental results could not be explained in terms of a Lewis-acid-catalyzed dehydrobromination.
