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 N‐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 (TMG2doo) in its diprotonated form and 2,2′‐bis[2N‐(1,1′,3,3′‐tetramethylguanidine)]diphenyleneamine (TMG2PA) as wellas N1,N3‐bis(dimorpholinomethylene)propane‐1,3‐diamine (DMorphG2p) as free bases. For the permethylated bis‐guanidine derivatives, the barrier to rotation around the (C=N)guanidine bond has been determined by means of temperature‐dependent EXSY 1H NMR spectroscopy to range between 54 and 79 kJ mol–1 depending on the type of spacer.

The complex anion was isolated as its PPh4‐salt 2b. The latter reacts with coinage metal complexes PPh3M2Cl [M2 = Cu, Ag, Au] to give chiral heterometallatetrahedranes of the general formula [Re2(AuPPh3)(M2PPh3)(μ‐PCy2)(CO)7C≡CPh] (M2 = Cu 3a, Ag 3b, Au 3c). The corresponding complex [Re2(AgPPh3)2(μ‐PCy2)(CO)7C≡CPh] (3d) is obtained from the reaction of [Re2(AgPPh3)2(μ‐PCy2)(CO)7Cl] (4) with LiC≡CPh. 3d undergoes a metathesis reaction in the presence of PPh3CuCl giving [Re2(AgPPh3)(CuPPh3)(μ‐PCy2)(CO)7C≡CPh] (3e) and PPh3AgCl. Analogous metathesis reactions are observed when 3c is reacted with PPh3AgCl or PPh3CuCl giving 3a or 3b, respectively. The reaction of 1 with PPh3AuCl gives benzaldehyde and Li[Re2(AuPPh3)(μ‐PCy2)(CO)7Cl] (5a) which upon reaction with PhLi forms the trinuclear complex Li[Re2(AuPPh3)(μ‐PCy2)(CO)7Ph] (6a). Again this complex was isolated as its PPh4‐salt 6b. In contrast to 2b, 6b reacts with one equivalent of Ph3PAuCl by transmetalation to give Ph3PAuPh and PPh4[Re2(AuPPh3)(μ‐PCy2)(CO)7Cl] (5b).
