Complexes of (C6F5)2Co and (C6F5)2Ni. Synthesis of (η6-arene)bis(pentafluorophenyl)cobalt(II) using cobalt atoms. Reactions, η6-arene lability, and use in synthesis of tetrahedral (C6F5)2Co(L)2

The high lability of the η6-arene ligand in (C6F6)2Co(η6-arene) has been used to advantage to prepare new (C6F5)2Co(L)2 and (C6F5)2Co(L-L) complexes (L = tetrahydrofuran, tetrahydrothiophene, and pyridine and L-L = bipyridine). According to spectral and magnetic data these are tetrahedral compounds. Similar π-arene displacements on (C6F5)2Ni(η6-arene) have yielded square-planar trans-(C6F5)2Ni(L)2 and square-planar cis-(C6F6)2Ni(L-L). The starting cobalt-arene complex induced the polymerization of norbornadiene and propyne. Thermolysis of the starting complex led to free radical decomposition, which is contrasted by nonradical reductive coupling with the nickel analogue. η6-Arene-exchange equilibria for the cobalt- and nickel-arene complexes indicated the order of preference for η6-arenes as mesitylene > toluene > benzene > anisole for cobalt and mesitylene > toluene ≈ anisole > benzene for nickel. A literature background regarding monoarene complexes is presented.
