Reactions of bromodurene and related compounds with strong bases: a novel 1,3-dehydrobromination
Abstract
Reaction of bromodurene (I) with potassium t-butoxide at 225° led to almost quantitative dehydrobromination to give durene (34%), t-butyl alcohol (74%), 2,4,5,2′,4′,5′-hexamethylbibenzyl and its mono- and dibromo-derivatives, similar reactions being observed with sodamide and with other related polymethylhalogenobenzenes.
