Abstract

The RCM of 1a in toluene took place at 80 °C in the presence of Ru-I, giving 2-phenyl-1-silaindene 2a in 17% yield (entry 1). The efficiency was significantly improved by the use of Ru-II, which afforded 2a quantitatively. When Mo was used as the catalyst, the RCM occurred at room temperature, giving 2a in 89% yield. Interestingly, a different catalyst profile was observed with 3-methoxyphenyl derivative 1b: Whereas similar results were obtained with the ruthenium ...
