Access to the Bis-benzene Cobalt(I) Sandwich Cation and its Derivatives : Synthons for a “Naked” Cobalt(I) Source?
(2018) In Angewandte Chemie - International Edition 57(30). p.9310-9314- Abstract
The synthesis and structural characterization of the hitherto unknown parent Co(bz)2
+ (bz=benzene) complex and several of its derivatives are described. Their synthesis starts either from a CoCO5
+ salt, or directly from Co2(CO)8 and a Ag+ salt. Stability and solubility of these complexes was achieved by using the weakly coordinating anions (WCAs) [Al(ORF)4]− and [F{Al(ORF)3}2]− {RF=C(CF3)3} and the solvent ortho-difluorobenzene (o-DFB). The magnetic properties of Co(bz)2

+ were measured and compared in the condensed and gas phases. The weakly bound Co(o-dfb)2
+ salts are of particular interest for the preparation of further CoI salts, for example, the structurally characterized low-coordinate 12 valence electron Co(PtBu3)2
+ and Co(NHC)2
+ salts.
