  α-CH Bond Activation of Coordinated Et₂O via Reaction of PR₃ (R = Ph, Cy) with the Cationic Complex [C₅Me₅W(CO)₃(OEt₂)]⁺

  摘要：

  Reaction of C(5)Me(5)W(CO)(3)CH3 (2) with [Et(2)O)(2)H](BAr4-)-B-+ (Ar = 3,5-bis(trifluoromethyl)phenyl) produced the new cationic complex [C(5)Me(5)W(CO)(3)(OEt(2))](BAr4-)-B-+ (1) in 82% isolated yield. The complex 1 readily undergoes ligand substitution reactions with neutral donor ligands to give the complexes [C(5)Me(5)N(CO)(3)(L)](BAr4-)-B-+ (L = CH3CN (3), MeOH (4), H2O (5)). In contrast, reaction of 1 with tertiary phosphines PR(3) (R = Ph, Cy) produced C(5)Me(5)W(CO)(3)H (6) and the new phosphonium salts EtOCH(Me)PR(3)(+)BAr(4)(-) (R = Ph (7), Cy (8)), where the alpha-CH of Et(2)O has been selectively displaced by phosphines.
