backbone was synthesized and fully characterized by mass spectrometry and NMR (1H, 13C, 31P) and IR spectroscopy. Gold bis-phospholane macrocycles containing 16 ([Au2Cl2(μ-3a)2], 4), 20 ([Au2Cl2(μ-3c)2], 5), 24 ([Au2Cl(μ-3e)2]Cl, 6), and 28 ([Au2Cl2(μ-3g)2], 7) atoms in the ring were obtained in one step from [AuCl(tht)] (tht = tetrahydrothiophene) and 3a,c,e,g in excellent yield. In addition, three polymers
