The underlying protocol can be used with predefined ureas as well as secondary amines to build up these units by reaction with phosgene if the ureas are otherwise unavailable. In the latter case, the resulting urea intermediates do not have to be isolated as the reaction proceeds further with additional phosgene to yield a chloroformamidinium chloride which is transformed into the bis‐guanidine functionality by subsequent reaction with a suitable primary diamine in the presence of triethylamine as an auxiliary base. This concept has been used to synthesise and characterise more then two dozen different bis‐guanidines based on 12 discrete monoguanidine units and seven different spacers. These spacers have been chosen such that the most important phenotypes have been dealt with and which range from rigid to more flexible scaffolds. In addition to spacers with no metal‐binding capabilities, other species containing further donor functions such as <jats:italic>N</jats:italic>‐methyldiphenyleneamine or pyridine‐2,6‐diyl have also been used. The substitution patterns of the guanidine residues can be classified into acyclic and cyclic types. Among the cyclic types, one subset is characterised by five‐ or six‐membered heterocycles containing both the amino nitrogen atoms and another one by individual N‐heterocyclic systems for each amino nitrogen. Structurally characterised examples are 2‐{2‐[2‐(tetramethylguanidi­no)ethoxy]ethoxy}‐1‐(tetramethylguanidino)ethane (TMG<jats:sub>2</jats:sub>doo) in its diprotonated form and 2,2′‐bis[2<jats:italic>N</jats:italic>‐(1,1′,3,3′‐tetramethylguanidine)]diphenyleneamine (TMG<jats:sub>2</jats:sub>PA) as wellas <jats:italic>N</jats:italic><jats:sup>1</jats:sup>,<jats:italic>N</jats:italic><jats:sup>3</jats:sup>‐bis(dimorpholinomethylene)propane‐1,3‐diamine (DMorphG<jats:sub>2</jats:sub>p) as free bases. For the permethylated bis‐guanidine derivatives, the barrier to rotation around the (C=N)<jats:sub>guanidine</jats:sub> bond has been determined by means of temperature‐dependent EXSY <jats:sup>1</jats:sup>H NMR spectroscopy to range between 54 and 79 kJ mol<jats:sup>–1</jats:sup> depending on the type of spacer.
