Abstract

Selective alkylation with trialkylaluminum compounds on the chlorine of tertiary alkyl chloride and bromide mixtures, and chlorobrominated alkanes has been studied. Using trimethylaluminum and mixtures of tert-butyl chloride and bromide, methylation selectivity is limited owing to the early methylation of tert-butyl bromide by the dimethylaluminum chloride by-product formed in the fast methylation of tert-butyl chloride. Similar results have been ...
