| Abstract: | Reactions of CH3Co(DH)2py (1) and Co(DH)2py]2 (2) with (CH3)2(CN)C (r) and (CH3)2(CN)COO (rO2) radicals were investigated. At 60°C, reaction or r with (1) results in non-homogeneous ligand decomposition, whereas for 2, complex (CH3)2CNCCo(DH)2py (6) and a precipitate are formed. Ligand decomposition also took place at 60°C when the reaction of rO2 radicals with 1 and 2 was investigated. However, the same reaction with rO2 radicals at −10°C, yielded two complexes, CH3OOCo(DH)2py (3) and Co(DH)2py (4) with 1, and complex 6 for the reaction of rO2 with 2. |
