Abstract
Novel acid systems are disclosed which are characterized as being capable of stabilizing high concentrations of tertiary cations, e.g., t-butyl cation, and further characterized as capable of forming carbonium ion salts containing both dimeric and monomeric anions. The ions undergo hydride and halide exchange with other alkanes and halides. The hydride transfer reaction renders them useful in isomerization and alkylation reactions.
