Synthesis of η1-butadienyl iron complex upon coupling of two organometallic η1-vinyl units and selective decomplexation at one end
摘要:
The symmetric binuclear iron mu-bis(ethylidene) complex [Cp*(dppe)Fe(=CHCH2CH2CH=)Fe(dppe)Cp*][PF6](2) (2) reacts with the equivalent of two KOBut in THF to provide the mononuclear eta(1)-butadienyl complex Cp*(dppe)Fe(CH=CH-CH=CH2) (4) isolated in 76% yield.
