Arenium Acid Catalyzed Deuteration of Aromatic Hydrocarbons Simon Duttwyler Anna M. Butterfield Jay S.

The reactions take place under ambient conditions in C<sub>6</sub>D<sub>6</sub> as an inexpensive deuterium source. High isolated yields and excellent degrees of deuterium incorporation were achieved using the substrates <i>p</i>-terphenyl, fluoranthene, pyrene, triphenylene, and corannulene. 2016-02-19 20:34:08 corannulene deuterium incorporation Arenium hydrocarbon mesitylene fluoranthene deuterium source triphenylene polycyclic ambient conditions catalyst substrate pyrene Catalyzed Deuteration C 6D yield High perdeuteration Aromatic HydrocarbonsThe arenium acid
