โฆ Synopsis
N-Haloelectrophiles react with alkenes in the presence of boron trifluoride etherate to give halofluorides and N-halo adducts.
There is a diverse group of positive halogen compounds containing the nitrogen-halogen bond. The group includes N-haloamines, N-haloamides, and N-haloimides. Although radical reactions of these compounds with alkenes are well-known, 1 their potential for ionic reactions has received little attention.
