Abstract
We report in the first IR observation of carbene complex Mo=CH2 on the surface of Mo/SiO2 metathesis catalyst. Mo=CH2 species were produced by cyclopropane chemisorption on catalysts, photoreduced in CO (Mo(IV)/SiO2), and are characterized in IR by C-H stretching vibrations at 3080 and 2945 cm−1.
