Hydrogen-deuterium exchange of heteroaromatics in neutral D2O at elevated temperatures

Werstiuk, Nick Henry,Timmins, George

, p. 1022 - 1024 (2007/10/02)

Pyridine (1), 2-methylpyridine (2), 3-methylpyridine (3), 4-methylpyridine (4), and 1,10.phenanthroline undergo H-D exchange in neutral D2O at elevated temperatures (180-300 deg C).With a suitable choice of temperature and reaction time it is possible to prepare selectively deuterated or perdeuterated substrates in good yield.
