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