Cu(2+)-l,8-Bis-(2-methoxycarbonylethylamino)-3,6-dithiaoctane Acetate (VII): A mixture of 2.1 g (6 mmole) of the diamine (III) and 0.54 g (3 mmole) of copper acetate in 50 ml of ethanol was stirred at 20~ for 3 h, the solution assuming a dark blue color. Most of the solvent was removed under reduced pressure, and the complex precipitated with ether. The oil which separated was kept under vacuum until
Cu(2+)-1,8-双-(2-甲氧基羰基乙基氨基)-3,6-二硫辛烷乙酸酯 (VII):2.1 g (6 mmole) 二胺 (III) 和 0.54 g (3 mmole) 的混合物将溶于 50 毫升乙醇的醋酸铜在 20 ℃下搅拌 3 小时,溶液呈深蓝色。减压除去大部分溶剂,用乙醚沉淀出络合物。将分离出的油保持在真空下直至其转化为玻璃状固体,产量为1.4g(90%)。红外光谱,cm-*:3200 (NH), 1730 (COOCHs)。实测值,%:C 40.1、H 6.2、N 4.9、S 11.6、Cu 11.5。C:.H3~N=OsS=Cu。计算,%:C 40.4、H 6.3、N 5.2、S 12.0、Cu 12.0。
