The deuteration and dedeuteration of 2,4,6-trimethylpyrylium perchlorate in water (D20 and HzO, respectively) was studied by nuclear magnetic resonance using as a quantitative standard for protons tetramethylammonium bromide. y-Methyl groups exchange faster than u-methyl groups; P-standing hydrogens

The HID exchange in 2,3-dimethylbenzothiazolium iodide was studied. The deuteration took place exclusively at the methyl group in position 2, and the non-catalyzed reaciion followed a first order kinetics.
Starting ,from the easily available 2,4,6-tri-d3-methyIpyrylium perchlorate, the .following methyl-deuterated compounds were prepared : 1,3-dimethylnaphthalene III, nitromesitylene I V, mesidine V, mesitylenediazonium hydrogen sulphate VI, mesitylene VII, mesitol VIII and I-mesityleneazo-2-naphthol
