One, two, three, four: A copper(I)-phosphine complex catalyzes the diborylation of alkynes and arynes, and the tri- or tetraborylation of propargyl ethers (see scheme; pin=pinacolato). In the latter cases, the C-O bond(s) as well as the C≡C bond are borylated in one pot. Furthermore, a diborylation product serves as an intermediate in the efficient synthesis of ortho-terphenyls with pharmacological activity.
