Synthesis of fluorinated amphoteric organoborons via iodofluorination of alkynyl and alkenyl MIDA boronates.

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.
