摘要

Aerosol direct fluorination of neopentyl chloride produces perfluoroneopentyl chloride in 74% yields. Analogous fluorination of neopentyl bromide produces perfluoroisopentane in 63% yield. Data are presented that support a carbocation rearrangement in the fluorination of neopentyl bromide. The carbocations are presumed to arise from disproportionation of neopentylbromine fluorides.
