Group activity: A novel copper-catalyzed fluorination of internal allylic bromides and chlorides has been developed by using Et3N×3 HF as the fluorine source. A functional group (FG) within the substrate is required to achieve the allylic fluorination, and a variety of secondary allylic fluoride compounds can be accessed in good yield with excellent regioselectivity.

Highly Stereoselective Route to (E)-Allyl Amines via Vinyltri-n-butylphosphonium Salts (Schweizer Reaction)
Meyers, A. I.,Lawson, Jon P.,Carver, David R.

The reaction of vinyltri-n-butylphosphonium salts, aldehydes, and sodiophthalimide in THF gave good yields of the allylic phthalimides with high E stereoselectivity (75-100percent).The use of the vinyltriphenylphosphonium salts (Schweizer reaction) gave the allyl phthalimide with the Z isomer predominating.A study of the phthalimide cation and the effect of added lithium salt showed some reversal in the olefin geometry but in general the selectivity was only 3:1
