Herein, the high yielding synthesis of the chiral carbodiphosphorane (3) prepared in a two‐step procedure from commercially available (R)‐BINAP (([1,1′‐binaphthalene]‐2,2′‐diyl)bis(diphenylphosphane), BINAP) and dibromomethane is presented. In the first reaction step, the bis phosphonium salt 1[Br]2 is obtained, which is subsequently deprotonated either with potassium hydroxide to yield the mono phosphonium salt 2[Br], or with potassium hexamethyldisilazanide to give 3. Moreover, coinage metal complexes of 3 were prepared via reaction with CuCl (4Cu, 5Cu, 6Cu), Cu(OTf)∙toluene0.5 (7Cu) or [AuCl(tht)] (5Au, 6Au). The prepared compounds were characterised by NMR‐ and IR‐spectroscopy, mass spectrometry, elemental analysis, single crystal X‐ray diffraction and UV/Vis spectroscopy. Photoluminescence emission spectra were obtained for most of the complexes ( 3, 4Cu, 5Cu, 6Cu and 6Au).
