Acid catalysis, general benzylic epoxides

General acid catalysis in the hydrolysis of 81 is quite facile. This reaction, as discussed in Section Benzylic epoxides and arene oxides and shown in Scheme 39, involves proton transfer to the epoxide oxygen concerted with epoxide C-O bond breaking to form a carbocation 83. For primary ammonium ions with pKa < 8, only the acid form of the amine is reactive, and carbocation formation is irreversible,... [Pg.98]
