Fluoro pyndines

This technique has been applied to the synthesis of fluormated dopamine and other compounds of biological significance Fluoroheterocycles such as fluoro-imidazoles [JJ, 36] and fluoropyrazoles [37] can also be prepared by the photo Balz-Schiemann technique (equation 9) Photochemically induced in situ fluoro dediazoniation can also be applied to arenediazonium fluorides in hydrogen fluo nde-pyndine media Thus, o-fluoroanisole is obtained in 73% yield at 20 °C after I8h [dS]... 

Halofluonnation of a-diazoacetophenone by N halosuccmimides in hydrogen fluonde-pyndine provides good yields of a-fluoro-a-haloacetopheiiones [6] (equation 24)...
