[Li(dime)₂][W(CO)₅I] as a novel synthon for the preparation of silyl, amino and organyl derivatives of pentacarbonyl tungsten (dime = diethylene glycol dimethyl ether)

Abstract

The one-pot reactions of M(CO)₆ with dime in the presence of LiI·Et₂O give [Li(dime)₂][M(CO)₅I] (M=W 1, Mo 2); the reaction of 1 with LiSiMe₂Ph, LiN(SiMe₃)₂ and PhCH₂MgCl affords the novel complexes [Li(dime)₂][W(CO)₅R] [R= SiMe₂Ph 3a, N(SiMe₃)₂ 3b, CH₂Ph 3c].
