Abstract
In this study, we report on the radical [F-18]fluoroarylation of different olefins using 4-[F-18]fluorobenzenediazonium ions to provide a new route to radiopharmaceuticals containing a deactivated, 4-[F-18]fluoro substituted phenyl group. This new methodology was shown to be well suited for the synthesis of F-18-labelled stilbenes. Stilbene 7 is now accessible within 80 min in 30-45% overall radiochemical yield starting from [F-18]fluoride. (C) 2008 Elsevier Ltd. All rights reserved.
