Abstract
Phosphabenzamidine [mes-NH-C(Ph)═P-mes) (1) and phosphaformamidine (mes-NH-CH═P-mes) (4) ligands have been synthesized and characterized. The conjugate bases of 1 and 4 coordinate by each bridging three Cu(I) ions, forming hexa- and tetranuclear clusters Cu[mes-N═C(Ph)-P-mes]ClLi(THF) (3) and Cu[mes-N═CH-P-mes] (5), respectively. Both clusters have been fully characterized using H NMR, P NMR, and X-ray crystallography. Complexes 3 and 5 exhibit a previously unknown coordination mode of phosphaamidinates, which are far less studied than their well-known amidinate counterparts.
摘要
Phosphabenzamidine [mes-NH-C(Ph)═P-mes) (1) 和 phosphaformamidine (mes-NH-CH═P-mes) (4) 配体已被合成并进行了表征。1 和 4 的共轭碱通过每个桥连三个 Cu(I) 离子配位，形成六核和四核簇 Cu[mes-N═C(Ph)-P-mes]ClLi(THF) (3) 和 Cu[mes-N═CH-P-mes] (5)。这两个簇都使用 1H NMR、31P NMR 和 X 射线晶体学进行了充分的表征。复合物 3 和 5 表现出以前未知的膦酰胺配体的配位模式，与广为人知的酰胺配体相比，它们的研究要少得多。
