The ring-closing metathesis (RCM) of bis(2-vinylphenyl)silanes in the presence of the second-generation Hoveyda–Grubbs catalyst in toluene at 100 °C afforded dibenzo[b,f]silepines in excellent yields. Other dibenzoheteropines of group 13–16 elements were also prepared via the RCM of the corresponding heteroatom-tethered dienes.
在第二代Hoveyda-Grubbs催化剂存在下,在100°C的甲苯中,双(2-乙烯基苯基)硅烷的闭环复分解(RCM)提供了极好的收率的二苯并[ b,f ]西拉品。还通过相应的杂原子连接的二烯的RCM制备了第13-16组元素的其他二苯并杂庚因。
