A new bulky facially coordinating N3-donor tach-based ligand (tach: cis,cis-1,3,5-triaminocyclohexane) [1: cis,cis-1,3,5-tris(2-fluoro-6-(trifluoromethyl)benzylideneamino)cyclohexane] has been obtained from the condensation of tach with 3 equiv of the appropriate benzaldehyde. Reaction of 1 with [Cu(NCMe)4][PF6] gave the complex [(1)Cu(NCMe)][PF6]. Displacement of the acetonitrile ligand is possible with CO and C2H4 (3-5 bar). Cu(I)-ethylene complexes of ligands 1 and 2 [2: cis,cis-1,3,5-(mesitylideneamino)cyclohexane] were prepared successfully by treatment of the ligands with CuBr and AgSbF6 in the presence of ethylene. These complexes display reversible complexation of the ethylene molecule under mild changes to pressure, suggesting possible application in olefin separation and extraction.
一种新的庞大的面配位 N3-供体 tach 为基础的配体（tach：顺式，顺式-1,3,5-三氨基环己烷）[1：顺式，顺式-1,3,5-三（2-氟-6-（三氟甲基）亚苄基氨基）环己烷]已从 tach 与 3 当量的适当苯甲醛的缩合获得。1 与[Cu（NCMe）4][PF6]的反应得到了配合物[(1)Cu（NCMe）][PF6]。乙腈配体的取代是可能的与 CO 和 C2H4（3-5 巴）。配体 1 和 2 的 Cu（I）-乙烯配合物[2：顺式，顺式-1,3,5-（均三甲苯基亚氨基）环己烷]通过用 CuBr 和 AgSbF6 在乙烯存在下处理配体成功制备。这些配合物在温和的压力变化下显示出乙烯分子的可逆络合，表明可能在烯烃分离和提取中有应用。
