Abstract

Treatment of [Cl(dppe)₂Ru–C [triple bond, length half m-dash] C–CC–SiMe₃] with [Fe(C₅H₅)₂]PF₆ leads to an unprecedented metal-assisted [2 + 2] coupling reaction on C^γC^δ bonds to obtain [Cl(dppe)₂Ru–CC–C [double bond, length half m-dash] CHC(CH₂)CCRu(dppe)₂Cl]PF₆ with the charge highly delocalized over seven carbon atoms and including a cyclobutenyl bridge; the crystal structure was solved.
