the corresponding di- or trinuclear copper(I) acetonitrile-phosphine complexes 1–5. Substitution of the labile acetonitrile groups with chelating aromatic diimines – 2, 2′-bipyridine (bpy), 1, 10-phenanthroline (phen), 5, 6-dimethyl-1, 10-phenanthroline (dmp), 5, 6-dibromo-1, 10-phenanthroline (phenBr2) – gives the corresponding substituted compounds 6–16. In all complexes 1–16 each central CuI atom
[Cu(NCMe)4]+ 与化学计量的二膦 R2P–(C6H4)n–PR2 (R = NC4H4, n = 1; R = Ph, n = 1, 2, 3) 或三膦 1 的反应, 3, 5-(PPh2–C6H4–)3–C6H3 配体得到相应的双核或三核铜 (I) 乙腈-膦配合物 1-5。用螯合芳族二亚胺取代不稳定的乙腈基团 – 2, 2'-联吡啶 (bpy), 1, 10-菲咯啉 (phen), 5, 6-二甲基-1, 10-菲咯啉 (dmp), 5, 6-二溴-1, 10-菲咯啉 (phenBr2) – 得到相应的取代化合物 6-16。在所有配合物 1-16 中,每个中心 CuI 原子都有四面体构型,由两个 N-和两个 P-供体基团完成。使用元素分析、ESI-MS、X 射线晶体学和 NMR 光谱对获得的化合物进行表征。所有膦-二亚胺化合物 6-16 在室温下在二氯甲烷溶液和固态(λex =
