[reaction: see text] Potassium bromo- and iodomethyltrifluoroborates have been prepared via in situ reaction of n-BuLi with dibromo- and diiodomethane, respectively, in the presence of trialkyl borates, followed by treatment with KHF(2). Moreover, a new synthetic method for the preparation
Reaction of 2-deoxy-6-O-[2,3-dideoxy-4,6-O-isopropylidene-2,3- (N-tosylepimino)-alpha-D-mannopyranosyl]-4,5-O-isopropylidene-1,3-di-N- tosylstreptamine with potassium hydrogenfluoride.

A number of alkynyl pinacolboronates bearing various functional groups were synthesized according to literature methods. These were then stereoselectively reduced to the cis-alkenyl pinacolboronates via hydroboration with dicyclohexylborane followed by chemoselective protodeboronation using acetic acid. Treatment with potassium hydrogen fluoride
