depend on the size of the halide ions, the solvent employed, and the reaction conditions. Copper(I) chloride formed a monomeric metallocyclophane, whereas copper(I) bromide and copper(I) iodide derivatives preferred dimeric and 1D-polymeric structures, respectively. The tricationic complexes derived from CuI ion and 2,4,6-tris(diphenylphosphino)-1,3,5-triazine also adopted monomeric metallocyclophane
通过使氰尿酰氯与3当量的三甲基甲硅烷基二苯基膦反应,以提高的产率制备了基于三嗪的三膦,2,4,6-三(二苯基膦基)-1,3,5-三嗪(1)。固态结构1的分子间P···P接触短,为3.362Å,明显短于磷原子的范德华半径之和(3.6Å)。2,4,6-三(二苯基膦基)-1,3,5-三嗪的反应(1)与铜(I)盐以2:3的摩尔比混合以定量收率得到各种环烷型配合物。已经发现这些簇的固态结构取决于卤离子的大小,所用溶剂和反应条件。氯化铜(I)形成单体金属环烷,而溴化铜(I)和碘化铜(I)衍生物分别优选二聚体和一维聚合结构。由Cu I离子和2,4,6-三(二苯基膦基)-1,3,5-三嗪衍生的三阳离子络合物也采用了单体金属环烷结构。这些配合物已用于微波辐射下的A 3偶联反应中。碘化亚铜(I)衍生物显示出优异的催化效率。
