InX3-catalyzed haloamidation of vinyl arenes: a facile synthesis of α-bromo- and α-fluoroamides
A variety of alkenes are converted into the corresponding α-fluoroamides in high yields by selectfluorTM in the presence of 10 mol % of InF3 in nitrile solution. α-Bromoamides are obtained with NBS in the presence of 10 mol % InBr3 under similar conditions. The use of Lewis acid in haloamidation significantly improved the yields and reaction rates.

Ritter-type fluorofunctionalisation as a new, effective method for conversion of alkenes to vicinal fluoroamides
A range of alkenes are converted to vicinal fluoroacetamides in high yield by reaction with 1-fluoro-4-hydroxy-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (Accufluor NFTh) in acetonitrile solution.
