Oxidn. of cobalt(I) carbonyl(hydride) (dippf)CoH(CO)2 1-H, dippf = 1,1'-bis(diisopropylphosphino)ferrocene gives 17-VE cation (dippf)CoH(CO)2+ (1-H+), which eliminates dihydrogen with formation of 16-VE cationic complex (dippf)Co(CO)2+ (1+). Crystal structures of 1-H and 1+PF6 are reported. The complex 1+PF6 can be also prepd. by chem. oxidn. of 1-H with ferrocenium hexafluorophosphate. The electrooxidn. process was followed with cyclic voltammetry and IR spectroelectrochem., which shows the intermediate formation of 1-H+. on SciFinder(R)
