Rearrangement of 2-Methylbutane-1-C^(14) over Aluminum Bromide

Abstract

Liquid-phase rearrangemeut of 2-methylbutane-1-C^(14) at room temperature over water-promoted aluminum brotmide appears to yield 2-methylbutane-4-C^(14) considerably more rapidly than 2-methylbutane-2(or 3)-C^(14). Very extensive rearrangement of C^(14) was observed in the conversion of 2-methylbutane-1-C^(14) to t-amyl bromide by treatment with t-butyl bromide and aluminum bromide even with a contact time of about 0.005 see. Photochemical vapor-phase halogenations of isopentane were found to give essentially pure t-amyl bromide with bromine and a serious mixture of products with chlorine.
