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 CO bond(s) as well as the CC bond are borylated in one pot. Furthermore, a diborylation product serves as an intermediate in the efficient synthesis of ortho‐terphenyls with pharmacological
一,二,三,四:铜(I)-膦配合物催化炔烃和芳烃的二硼化,以及炔丙基醚的三硼化或四硼化(参见方案; pin = pinacolato)。在后一种情况下,将C O键(一个或多个)以及所述CC键被borylated一锅。此外,二氢甲酰化产物是有效合成具有药理活性的邻三联苯的中间体。
