Nickel-Catalyzed trans-Alkynylboration of Alkynes via Activation of a Boron−Chlorine Bond

Reaction of (diisopropylamino)chloroboryl ethers of alkynols with alkynylstannanes in the presence of nickel catalysts afforded formal trans-alkynylboration products in good yields. The products were isolated as pinacol boronates after treatment of the crude reaction mixture with acetic anhydride an...
