在 5–10 mol % [Cp*RuCl2]n 存在下，炔烃与双(频哪醇)二硼 (B2pin2) 反应，得到相应的 (Z)-1,2-二硼基烯烃。添加 30 mol % NaOC6H4(4-tBu) 和 2–5 当量。甲醇对于反应以高产率进行至关重要。该反应中使用了各种炔烃，所得1,2-二硼基烯烃用作四取代烯烃的前体。
Alkynes react with bis(pinacolato)diboron (B2pin2) in the presence of 5–10 mol % [Cp*RuCl2]nto afford the corresponding (Z)‐1,2‐diboryl alkenes. The addition of 30 mol % NaOC6H4(4‐tBu) and 2–5 equiv. of methanol was essential for the reaction to proceed with high product yield. Various alkynes were employed in the reaction, and the obtained 1,2‐diboryl alkenes were used as precursors for tetrasubstituted alkenes.
