title: Rapid, microwave-assisted perdeuteration of polycyclic aromatic hydrocarbons.
abstract: A simple and convenient method for the perdeuteration of polycyclic aromatic hydrocarbons that does not require strong acid has been developed. Using commercially available reagents, the one-step procedure provides a new route to perdeuterated derivatives of both common and exotic polycyclic aromatic hydrocarbons. Microwave irradiation of the hydrocarbons in a solution of dimethylformamide-d7 containing potassium tert-butoxide affords rapid and essentially complete H/D exchange. For example, corannulene is converted to corannulene-d10 with >98% deuterium incorporation in just 1 h of microwave irradiation in a solution of t-BuOK/DMF-d7.
