Abstract
Complexes mer-CoH(CO-CR=CR'-O)(PMe3)(3) react with haloalkanes RX (X = Br, I) or with acids HX (X = Cl, Br) under elimination of dihydrogen. In both reactions a change of configuration at the metal is brought a bout by directional steering through the hard/soft (acyl)enolato chela te ligands to form octahedral complexes mer-CoX(CO-CR=CR'-O)(PMe3)(3) or sterically crowded ionic compounds [Co(CO-CR=CR'-O)(PMe3)(4(3))](+) X- (X = ClO4) without opening of the (acyl)enolato chelate ring.
