Abstract

Routes to new tungsten alkylidene complexes that contain tert-butylimido or adamantylimido ligands have been devised that begin with a reaction between WCl ₆ and 4 equivalents of HNR(TMS) to give [W(NR) ₂Cl(μ- Cl)(RNH ₂)] ₂ (R = t-Bu or 1-adamantyl). Alkylation leads to W(NR) ₂(CH ₂R′) ₂ (R′ = t-Bu or CMe ₂Ph), which upon treatment with pyridinium chloride yields W(NR)(CHR′)Cl ₂(py) ₂ complexes, from which W(NR)(CHR′)(pyrrolide) ₂ and two W(N-t-Bu)(CHR′) (pyrrolide)(OAr) complexes (OAr = hexamethyl- or hexaisopropylterphenoxide) have been prepared.
