摘要

The thermal decomposition of aryl diazonium tetrafluoroborates or hexafluorophosphates (the Baltz-Schiemann reaction and variants, Scheme I) is widely used as a method for preparing aromatic fluoro compounds.'Within certain structural and functional constraints, yields vary from moderate to good. lb The Baltz-Schiemann reaction, however, is not well suited for fluorination with the short-lived, positron-emitting radionuclide fluorine-18 (tlIz= ...
