The present invention relates to a method to extract out of an aqueous solution, concentrate and/or reformulate [18F] fluorides without any evaporation step, characterised in that the eluting solution is a low water content, preferably <3% water, organic solution containing at least:
- a first compound (A) which is a tertiary alcohol-function bearing molecule,
- a second compound (B) which is a phase transfer agent suitable for radiolabeling and which is necessary to the anion exchange process.

S(N)2' (gamma) substitutions of delta-substituted allylicacetates with Grignard reagents and copper catalysts proceed with high diastereoselectivities. With benzyloxy, methoxymethoxy, and tert-butyldimethylsiloxy groups, reactions favor the anti-isomer with selectivities up to anti:syn = >99:1. With a hydroxyl group, selectivities are reversed and the syn-isomer is favored with selectivities up to
