摘要：
(Chemical Equation Presented) A bit unusual: "Abnormal" carbene formation from a free monodentate N-heterocyclic carbene occurs upon the room temperature reaction of [Ru3(CO)12] with 1,3-di-tert-butylimidazol-2-ylidene. Subsequent heating leads to C-H activation at the remaining C5 position to afford a μ3-bridging heterocycle, which is eliminated as imidazolium upon reaction with H2. © 2007 Wiley-VCH Verlag GmbH & Co.
