Arenium Acid Catalyzed Deuteration of Aromatic Hydrocarbons
journal contribution
posted on 2016-02-19, 20:34 authored by Simon Duttwyler, Anna M. Butterfield, Jay S. SiegelThe arenium acid [mesitylene–H]+ has
been shown
to be an extraordinarily active H/D exchange catalyst for the perdeuteration
of polycyclic aromatic hydrocarbons. The reactions take place under
ambient conditions in C6D6 as an inexpensive
deuterium source. High isolated yields and excellent degrees of deuterium
incorporation were achieved using the substrates p-terphenyl, fluoranthene, pyrene, triphenylene, and corannulene.
