A bidentate NHC - alkenyl ruthenium(II) complex has been obtained on deprotonation of imidazolium salts with a N-CH2CH2X branch (X = OMe, Cl) followed by reaction with [RuCl2(p-cymene)] 2. Low-temperature NMR studies and intermediate trapping with BH 3 indicate the formation of a CH2= CH - NHC carbene followed by the intramolecular activation of a vinyl sp2 C - H bond on coordination to a ruthenium(II) center.
