DOIAbstract
The reaction of the stable N-heterocyclic silylene [CH{(CCH<sub>2</sub>)(CMe)(2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>N)<sub>2</sub>}Si] (<b>1</b>) with triphenylsilanol and pentafluorophenol in a 1:2 molar ratio resulted in quantitative yields of the pentacoordinate silicon-containing compounds [CH{(CMe)<sub>2</sub>(2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>N)<sub>2</sub>}Si(H){OSiPh<sub>3</sub>}<sub>2</sub>] (<b>2</b>) and [CH{(CMe)<sub>2</sub>(2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>N)<sub>2</sub>}Si(H){OC<sub>6</sub>F<sub>5</sub>}<sub>2</sub>] (<b>3</b>), respectively. Compounds <b>2</b> and <b>3</b> were formed by O–H bond activation of triphenylsilanol and pentafluorophenol. They were cha...
