Abstract
Abstract The Grubbs second generation catalyst [RuCl2(PCy3)(H2IMes)CHPh] was analysed in solution in order to identify and assign all of the 1H and 13C NMR resonances. This was achieved through utilizing various 2D NMR techniques and by acquiring spectra at a range of different temperatures (−40 to 60 °C). These assignments will aid researchers in future NMR studies of catalytic systems that employ the Grubbs catalyst by eliminating the resonances belonging to the catalyst and thus enabling the identification of any intermediates and/or new catalytic species. Restricted conformations and π-stacking arrangement within the catalyst was also confirmed during this study.
