Reaction Of The N-Heterocyclic Carbene, 1,3-Dimesityl-Imidazol-2-Ylidene, With A Uranyl Triflate Complex, Uo2(Otf)(2)(Thf)(3)
APPLIED ORGANOMETALLIC CHEMISTRY(2006)
摘要
The N-heterocyclic carbene, 1,3-dimesityl-imidazol-2-ylidene (IMes) reacts with tetrahydrofuran (THF) in the presence of an oxidizing uranyl triflate complex, UO2(OTf)(2)(thf)(3) (-OTf = -OSO2CF3), to give 1,4-bis(1,3-dimesityl-2-imidazolium)-1,3-butadiene bis(trifluoromethanesulfonate), formally understood as the coupling product of two equivalents of IMes with [CH = CH - CH = CH](OTf)(2).
