Abstract

The on-surface dimerization reaction of an organic nitrile on Au(111) is reported. The formation of the product{,} which contains five newly formed σ-bonds and a diazapyrene core structure{,} was investigated and characterized by scanning tunneling microscopy. Experimental and computational studies of reference compounds support our findings.
