Aminovinylidene: A Stable Surface Intermediate in the Dehydrogenation of Ethylamine on Pt(1 1 1)



original image

The midway point: The dehydrogenation of ethylamine on Pt(1 1 1) generates a stable surface intermediate, which was identified by reflection absorption infrared spectroscopy and density functional theory calculations as aminovinylidene. It is a novel surface species with a π-bond delocalized across its three atomic centers.
