Abstract

Abstract: The reaction of cyclo ‐P4 Mes4 C(NCy) (1 ) with two equivalents of [AuCl(tht)] (tht=tetrahydrothiophene) resulted in the formation of unusual sixteen‐membered Au–P macrocycle2 . This macrocycle contains diphospha(III)guanidinate as a coordinating ligand, which is formed by P−P bond cleavage of1 . Macrocycle2 was characterized by multinuclear NMR spectroscopy, mass spectrometry and X‐ray crystallography.
