| Abstract: | Dimethyl 5‐aminoisophthalate, which is a building block of amino‐substituted tetralactam macrocycles, was used as ligand in gold(I) chemistry to form model complexes for macrocyclic gold compounds. Reaction of dimethyl 5‐aminoisophthalate with chlorodiphenylphosphine gave the diphosphine compound dimethyl 5‐N,N‐bis(diphenylphosphanyl)amino]isophthalate (dmbpaip). This compound can further be reacted with AuCl(tht)] (tht = tetrahydrothiophene) to give the dinuclear complex Au2Cl2(dmbpaip)]. In contrast, treatment of dmbpaip with Au(tht)2]ClO4 resulted in the ionic compound Au2(dmbpaip)2](ClO4)2 in which the cation forms an eight‐membered Au2P4N2 heterocycle. In both gold(I) compounds Au···Au interactions are observed. All new compounds were characterized by single‐crystal X‐ray diffraction. |
