A powerful Fe(III)/NaBH(4)-mediated freeradical hydrofluorination of unactivated alkenes is disclosed using Selectfluor reagent as a source of fluorine and resulting in exclusive Markovnikov addition. In contrast to the traditional and unmanageable freeradical hydrofluorination of alkenes, the Fe(III)/NaBH(4)-mediated reaction is conducted under exceptionally mild reaction conditions (0 °C, 5 min

The invention describes novel direct synthesis methods for converting a precursor into a PET-tracer with a
18
F-fluoromethoxy-group. The invention is also directed to novel and stable precursors for the direct radiosynthesis of protected derivatives of O—([
18
F]Fluoromethyl)tyrosines.
