Syntheses And Reactivity Studies Of Square-Planar Diamido-Pyridine Complexes Based On Earth-Abundant First-Row Transition Elements
INORGANIC CHEMISTRY(2015)
Abstract
The new square-planar complexes M[NNN]-(pyridine) (M = Fe (1), Co(2); NNN = 2,6-bis(2,6-diisopropylphenylamidomethyl)pyridine) were synthesized and fully characterized to investigate small molecule activation on this platform and also associated ligand innocence. The equatorial pyridine solvent moiety could not be removed; a new bis-ligand species Co [NNN center dot H](2) (3) was synthesized in low yield while attempting to make the base-free derivative. Attempts to prepare the Ni analogue of 1 and 2 instead yielded crystals of a di-imino-pyridine complex Ni[PDI]Cl (4) (PDI = 2,6-bis(2,6-diisopropylphenyliminomethyppyridine), following loss of methylene backbone hydrogen atoms. Structural analysis indicates that the PDI ligand is a mono-anionic radical. This susceptibility of the ligand to oxidative dehydrogenation was also shown when the reaction of 2 with 2 equiv of trityl chloride yielded a new complex with an asymmetric imino amino pyridine ligand Co[NNN']Cl-2 (5) (NNN' = 2-(2,6-(diisopropylphenyliminomethyl)-6-(diisopropylphenylamidomethyl)-pyridine) in good yield.
