Evilia, Ronald F.,Pan, Dawei,Timberlake, Jack W.,Whittenburg, Scott L.

, p. 871 - 874 (1991)

The reactions of 2-mesityl-2-propanol (2) and 2-mesityl-1-propene (6) have been investigated with the objective of evaluating the effect of ortho methyl groups on chemical reactivity.The 13C NMR spectrum of 2-mesityl-2-propyl cation (3) indicates the expected steric inhibition to resonance.
