Development of 18F-labeled trifluoroboroaryl-functionalized PAMAM dendron/biotin conjugates for targeting of HER-2 expressing cancer cells pretreated with avidin-conjugated antibody
Preparation of tetrabutylammonium trifluoroborates
Used as a nucleophile for charge delocalization and enhanced acidity in tricationic superelectrophiles
Reagent used to prepare potassium organotrifluoroborates from their corresponding boronic acids.[1]
[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

E-allylic boronic esters undergo a highly diastereoselective protodeboronation with TBAF⋅3 H(2)O to give Z-trisubstituted alkenes. The selectivity can be switched to give predominantly the E-alkene instead by using KHF(2)/TsOH (see scheme). The utility of the methodology has been illustrated in a
