15.1.1.4.1.1.1.1 Method 1: Base-Induced Hydrogen–Deuterium Exchange

DOI: 10.1055/sos-SD-015-00002

Spitzner, D.Science of Synthesis, (200515140.

The base-induced hydrogendeuterium exchange in pyridine is much easier than in ­benz­ene, with the hydrogen at the 4-position of pyridine being easier to exchange than H3 or H2.[‌699‌,‌700‌] Direct hydrogendeuterium exchange of pyridines with deuterium oxide can be effected at 200 to 400°C.
