Reversible Complexation of Lewis Bases to Low-Coordinate Fe(II), Co(II), and Ni(II) Amides: Influence of the Metal, Donor Ligand, and Amide Substituent on Binding Constants
Philip P. Power, Chun-Yi Lin, James C. Fettinger
The binding constants of several Lewis bases [L = tetrahydrofuran (THF), tetrahydrothiophene (THT), pyridine, 4-(dimethylamino)pyridine (DMAP), PMe3, PCy3, and 1,3-bis(1,3,5-trimethylphenyl)imidazol-2-ylidene (IMes)] to the two-coordinate transition-metal complexes, M{N(SiMe3)Dipp}2 (M = Fe, Co, and Ni), were determined by electronic absorption spectroscopy. The binding strengths were in the order of DMAP > pyridine > PMe3 > PCy3 ≈ IMes > THF > THT, and those of the respective metals were in the order of Fe > Co > Ni. The binding constants of THF to M{N(SiMe3)2}2 (M = Fe or Co) were also determined by electronic absorption and 1H NMR spectroscopy studies.
