Synthesis of aryl allylic fluorides by direct electrophilic fluorination of alkenes
摘要:
Aryl allylic fluorides were synthesized in 47-83% yields by using Selectfluor as the electrophilic reagent in DMF. The outcome of this reaction may be explained by electronic effects while the reactivity was controlled by the stabilization effect of the aryl group on the benzylic cationic intermediates.
