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 macrocycle 2. This macrocycle contains diphospha(III)guanidinate as a coordinating ligand, which is formed by P-P bond cleavage of 1. Macrocycle 2 was characterized by multinuclear NMR spectroscopy, mass spectrometry and X-ray crystallography.

Keywords: P ligands; diphospha(III)guanidine; gold; macrocycles; phosphorus.
