title: Carbon-carbon bond activation by 1,1-carboboration of internal alkynes.
abstract: Internal alkynes undergo 1,1-carboboration reactions upon treatment with boranes RB(C(6)F(5))(2) (R = C(6)F(5), CH(3)) to yield trisubstituted alkenylboranes. These products can be used as substrates in Pd-catalyzed cross-coupling reactions.
