Abstract: Kinetics and product distributions resulting from the competitive reactions of the primary y, y-dimethylallyl chloride and of the allylically isomeric tertiary a, a-dimethylallyl chloride with solvent and sodium azide in 80% aqueous acetone at 32.0” have been studied. Both substrates undergo a kinetically second-order reaction with sodium azide, the reaction with the tertiary substrate being either bimolecular attack at tertiary carbon or a ...
