Patent Abstract

Die Einführung von [18F]Fluoridionen in den aromatischen Kern von Phenylazocarbonsäureestern kann in sehr kurzen Reaktionszeiten und mit hohen radiochemischen Ausbeuten erreicht werden. Zum Zweck der Markierung können die erhaltenen, 18F-fluorsubstituierten Azoester weiter in radikalischen oder Substitutionen an ihrer Carbonyleinheit umgesetzt werden, um Azocarboxamide zu erhalten.
