(Acylphenolato)hydridocobalt(III) complexes by reaction with (2-diphenylphosphanyl) phenol deliver (2-diphenylphosphanyl)phenolatocobalt(III) complexes with a 2-acylphenolato chelating ligand as co-ligand (complexes 2, 4-6, and 10-12). Depending on the substituents in the chelating ligands trans/cis-isomers were detected by NMR and IR spectroscopy. Complex 2 was shown by X-ray crystallography to attain an octahedral structure. Under specific conditions substituted (2-hydroxymethyl)phenol and a (2-diphenylphosphanyl)- phenolatocobalt(I) complex were obtained. A likely reaction route is presented. Influences of chelating ligands containing hard/soft donor atoms on the stability of the cobalt complexes will be discussed.
