hexaamines have been isolated and characterized as major by-products. The complexation of Cu(I) by the triamines has been studied potentiometrically in CH3CN/H2O. All ligands L form ternary complexes [Cu(CH3CN)L]+. The corresponding association constants vary between 1011 and 107, decreasing with increasing ring size. In addition, complexes [Cu(CH3CN)yLH]2+, y = 1 or 2, are found as less important species
通过对甲苯磺酸法合成了8个环大小在9至13之间的环状三胺。开链三胺双(2-氨基乙基)胺(dien)和双(3-氨基丙基)胺(二丙醇)用作起始原料。在某些情况下,相应的二聚环己胺已被分离出来并表征为主要副产物。已经在CH 3 CN / H 2 O中对三胺与Cu(I)的络合物进行了电位分析。所有配体L形成三元络合物[Cu(CH 3 CN)L] +。相应的缔合常数在10 11和10 7之间变化,随环尺寸的增加而减小。此外,络合物[Cu(CH 3 CN)y LH] 2 +, y = 1或2,是次重要的物种,最大浓度为7%至50%。
