Here we present a combined study using scanning tunneling microscopy and X-ray photoelectron spectroscopy under ultra-high vacuum to explore covalent bond formations on close-packed Ag, Au, Cu, and Pt single crystal surfaces. Besides the investigation of metal-organic interactions of a cyclic peptide, the main goal was to achieve and optimize covalent nanostructures via imine formation, Ullmann coupling and carbene formation. The most promising results were found for imine formation on Ag and for a prototypical N-heterocyclic carbene, which universally formed monolayers of bis-carbene metal adatom complexes.
