A Novel Isomerization of an Electron-Rich Alkene

Displacement of 2-methvlpropene from [Fp(Me C = CH )]BF (Fp = (η -C )Fe(CO) ) by Z-1,2-dimethoxyethylene (Z-DME) gives [Fp(Z-DME)]BF . Displacement by E-1,2-dimethoxyethylene (E-DME), in contrast, does not give the expected complex of E-DME, but rather the complex of the Z-alkene. A mechanism involv...

Zusammenfassung:Displacement of 2-methvlpropene from [Fp(Me C = CH )]BF (Fp = (η -C )Fe(CO) ) by Z-1,2-dimethoxyethylene (Z-DME) gives [Fp(Z-DME)]BF . Displacement by E-1,2-dimethoxyethylene (E-DME), in contrast, does not give the expected complex of E-DME, but rather the complex of the Z-alkene. A mechanism involving scission of the C = C bond of the coordinated alkene to give a bis-carbene intermediate is proposed.
