Secondary Coordination Sphere Influence on the Reactivity of Nonheme Iron(II) Complexes: An Experimental and DFT Approach
摘要:
The new biomimetic ligands N4Py(2Ph) (1) and N4Py(2Ph,amide) (2) were synthesized and yield the iron(II) complexes [Fe-II(N4Py(2Ph))(NCCH3)](BF4)(2) (3) and [Fe-II(N4Py(2Ph,amide))](BF4)(2) (5). Controlled orientation of the Ph substituents in 3 leads to facile triplet spin reactivity for a putative Fe-IV(O) intermediate, resulting in rapid arene hydroxylation. Addition of a peripheral amide substituent within hydrogen-bond distance of the iron first coordination sphere leads to stabilization of a high-spin (FeOOR)-O-III species which decays without arene hydroxylation. These results provide new insights regarding the impact of secondary coordination sphere effects at nonheme iron centers.

A series of novel mono-substituted and summetrically tri-substituted tris(2-pyridyl)methanols have been prepared in a one-step reaction from the corresponding 2-bromopyridines. Metal complexes of these compounds and their further functionalised derivatives are of interest as carbonic anhydrase (CA) mimics.

selective detection of mismatched DNA. Increased steric bulk of the tetraarylethylene ligands in these complexes was observed to correlate with greater preferential luminescence enhancement in the presence of hairpin DNA oligonucleotides containing a mismatched site compared to well-matched oligonucleotides, with the most effective complex displaying ∼14-fold higher emission upon binding CC mismatched oligonucleotides
The present invention describes novel metal complexes with bipolar ligands. Compounds of this type can be employed as functional materials in a number of different applications which can be ascribed to the electronics industry in the broadest sense.
