The ring-closingmetathesis (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.
