On‐surface reactions based on metal‐catalysed Ullmann coupling have been successfully employed to synthesise a wide variety of covalently coupled structures. Substrate chemistry and topology are both known to effect the progression of an on‐surface reaction; offering routes to control efficiency and selectivity. Here, we detail ultra‐high vacuum scanning probe microscopy experiments showing that templating a catalytically active surface, via a supramolecular template, influences the reaction pathway of an on‐surface Ullmann‐type coupling reaction by inhibiting one potential intermediate structure and stabilising another.
