Wittig-like reactions of tungsten alkylidyne complexes

W(C-t-Bu)(DIPP)3 (DIPP = 2,6-diisopropylphenoxide) reacts rapidly with acetonitrile to give [W(N)(DIPP)3]x and t-BuC≡CMe. It reacts with acetone, benzaldehyde, paraformaldehyde, ethyl formate, and N,N-dimethylformamide to give oxo vinyl complexes of the type W(O)(t-BuC=CR1R2)(DIPP)3. The tungstenacyclobutadiene complex W(C3Et3)(DIPP)3 reacts similarly with acetone, benzaldehyde, ethyl formate and N,N-dimethylformamide to give complexes of the type W(O)(EtC=CR1R2)(DIPP)3. The oxo vinyl complexes can be hydrolyzed by base to yield the expected olefinic product in good to excellent yield. The olefin product is mainly the cis isomer in most cases.
