Abstract The synthesis and structural characterization of the copper salts [Cu 2 (2-Boc-benzoate) 4 (dme) 2 ] ( 1 ), [Cu(2-Boc-benzoate) 2 (tmeda)] ( 2 ), [Cu 2 (2-Boc-benzoate) 2 (dppm)] ( 3 ), [Cu(2-Boc-nicotinate)(PPh 3 ) 2 ] ( 4 ), [Cu 2 2-Boc-5,6-anhydride-naphthylcarboxylate} 2 (dppm) 2 ] ( 5 ) [dme = 1,2-dimethoxyethane, dppm = bis(diphenylphosphino)methane, tmeda = N , N ′-tetramethylethylenediamine
摘要铜盐[Cu 2(2-Boc-苯甲酸酯)4(dme)2](1),[Cu(2-Boc-苯甲酸酯)2(tmeda)](2),[Cu 2(2-Boc-苯甲酸酯)2(dppm)](3),[Cu(2-Boc-烟酸酯)(PPh 3)2](4),[Cu 2 2-Boc-5,6-酸酐-萘甲酸} 2(dppm)2](5)[dme = 1,2-二甲氧基乙烷,dppm =双(二苯基膦基)甲烷,tmeda = N,N'-四甲基乙二胺,Boc =叔丁氧羰基]证明了环状有机酸酐和二酐易于插入[CuO t Bu]的Cu-O键中,形成在配体外围具有酯官能团的羧酸酯配体。通过Sb(OMe)3与邻苯二甲酸酐的插入反应合成了[Sb(CO 2 Ph-o-CO 2 Me)2(OMe)(tmeda)](6)。
