Calix[n]arenes (n = 4, 6) existing in the cone, 1,3-alternate or 1,3,5-alternate conformations and functionalized by two, four or six Bu2P(O)CH2O groups have been synthesized by the alkylation of hydroxycalix[4,6]arenes with tosylate of dibutylhydroxymethylphosphine oxide. Their molecular and crystal structures as well as binding properties towards of heterometallic Ru/Zn complexes were investigated. Due to the “calixarene effect” the phosphine oxides are effective extractants for the Ru/Zn complexes.
通过羟基钙[4,6]烯与二丁基羟甲基氧化膦的对甲苯磺酸盐的烷基化,合成了锥形、1,3-互变或 1,3,5-互变构象的钙[n]烯(n = 4, 6),并使其具有两个、四个或六个 Bu2P(O)CH2O 官能团。研究了它们的分子和晶体结构以及与异金属 Ru/Zn 配合物的结合特性。由于 "卡利沙林效应",膦氧化物是 Ru/Zn 复合物的有效萃取剂。
