  Cp*(PiPr₃)RuOTf: A Reagent for Access to Ruthenium Silylene Complexes

  摘要：

  The ruthenium triflate complex Cp*(PiPr(3))RuOTf (1) was generated from the reaction of Cp*(PiPr(3))RuCl with Me3SiOTf in dibutyl ether. Complex 1 reacted with primary and secondary silanes to produce a family of Ru(IV) silyl dihydride complexes of the type Cp*(PiPr(3))Ru(H)(2)(SiRR'OTf) (3-12). Structural analyses of complexes 8 (R = R' = Ph) and 12 (R = R' = fluorenyl) revealed the presence of a tetrahedral silicon center and a four-legged piano stool geometry about ruthenium. Anion abstraction from Cp*(PiPr(3))Ru(H)(2)(SiHROTf) by [Et3Si center dot toluene][B(C6F5)(4)] afforded hydrogen-substituted cationic ruthenium silylene complexes [Cp*(PiPr(3))Ru(H)(2)(=SiHR)][B(C6F5)(4)] (R = Mes (13), R = Si(SiMe3) (14)) that display a significant Ru-H center dot center dot center dot Si interaction, as indicated by relatively large (2)J(SiH) coupling constants ((2)J(SiH) = 58.2 Hz (13), (2)J(SiH) = 37.1 Hz (14)). The syntheses of secondary silylene complexes [Cp*(PiPr(3))Ru(H)(2)(=SiRR')][B(C6F5)(4)] (R = R' = Ph (15); R = Ph, R' = Me (16), R = R' = fluorenyl (17)) were also achieved by anion abstraction with [Et3Si center dot toluene] [B(C6F5)(4)]. Complexes 15-17 do not display strong Ru-H center dot center dot center dot Si secondary interactions, as indicated by very small (2)J(SiH) coupling constant values.
