The selective copper‐catalyzed borylation of silylalkynes in the presence of a diboron reagent and methanol produced a variety of (Z)‐β‐(borylvinyl)silanes. The appropriate use of a selective ligand for copper allows the chemo‐, regio‐, and stereoselective monoborylation of silylalkynes. The β‐regioselectivity of an N‐heterocyclic carbene (NHC)‐copper catalyst was investigated by DFT calculations.
在存在二硼试剂和甲醇的情况下,铜催化的甲硅烷基炔烃的选择性硼化反应生成了各种(Z)-β-(硼乙烯基乙烯基)硅烷。铜的选择性配体的适当使用可实现甲硅烷基炔的化学,区域和立体选择性单硼化。通过DFT计算研究了N-杂环卡宾(NHC)-铜催化剂的β-区域选择性。
