Keywords: on-surface reaction; scanning tunneling microscopy; trimesic acid; undecan-1-ol; Introduction On-surface reactions are a widespread class of chemical reactions taking place on a surface or at an interface involving active participation of two-dimensional molecular entities. This

• other already in a quite favorable relative orientation for a subsequent reaction. That is the “flat approach” (almost 2-dimensional) necessary as shown in the simulation as the free molecules correspond fairly well also to the experimental situation of the on-surface reaction considered experimetally

• esterification takes place at the interface; or 3) the esterification observed here is a typical on-surface reaction. Concerning 1): ESIMS analysis (see Supporting Information File 1) showed some traces of the ester after sufficiently long sonication time due to an initiated reaction in the bulk of the solution
