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. %I ACS Publications
