IR spectroscopic monitoring of the reaction between 1Mes and carbon monoxide. a IR spectra in toluene at room temperature obtained from the reaction of 1Mes with CO; an aliquot was taken from the reaction mixture at the indicated times, dried under vacuum for ca. 1 h and dissolved in toluene. b Zoom of a between 1800 and 1550 cm–1; spectra recorded at 6 days and 9 days. c IR spectra in toluene at room temperature obtained from the reaction of 1Mes with 13CO; an aliquot was taken from reaction mixture at the indicated times, dried under vacuum for ca. 1 h and dissolved in toluene
