The difunctionalization of terminal alkynes was achieved with silver fluoride (AgF) and N-bromosuccinimide (NBS) as halogen sources. The presence of the halide moiety greatly enhances the reactivity of the vinyl fluoride compounds that can probably can be transformed into various products that are difficult or even impossible to obtain via direct fluorination. Meanwhile, the monofluoro<.>alkenes were

The iodofluorination of alkynyl and alkenyl MIDA (N-methyliminodiacetyl) boronates led to the synthesis of two types of fluorinated organoborons bearing a valuable C–I bond. The B(MIDA) moiety confers exclusive regioselectivity to the reaction, and the products were formed in generally good yields. Preliminary utility of the products was demonstrated.
