Abstract

Mo(PMe ₃) ₆ and W(PMe ₃) ₄(η ³-CH ₂PMe ₂)H react with the diphenol CH ₂(Ai ^Me2OH) ₂ (Ar ^Me2 = C ₆H ₂Me ₂) to yield [x?,rfCH ₂(Ar ^Me2O) ₂]M(PMe ₃) ₃H ₂ (M = Mo, W), which possess agostic M - H - C interactions. NMR spectroscopic studies provide evidence that the tungsten compound is in facile equilibrium with the metalated trihydride [κ ³CH(Ar ^Me2O) ₂]W(PMe ₃) ₃H ₃.
