Carbon−Carbon Bond Activation by 1,1-Carboboration of Internal Alkynes

Carbon−Carbon Bond Activation by 1,1-Carboboration of Internal Alkynes

Internal alkynes undergo 1,1-carboboration reactions upon treatment with boranes RB(C6F5)2 (R = C6F5, CH3) to yield trisubstituted alkenylboranes. These products can be used as substrates in Pd-catalyzed cross-coupling reactions.
