TL;DR: A model for the key intermediate in copper oxygenase reactions, the Cu(II)-OOH complex, was prepared with the novel tripodal pyridylamine ligand, bis(6-pivalamide-2-pyridylmethyl)(2- pyridolmethyl)amine, stabilized by hydrogen bonding to two amine H atoms.
Journal ArticleDOI
SOD activities of the copper complexes with tripodal polypyridylamine ligands having a hydrogen bonding site
TL;DR: In this paper, a structural mimic of the Arg 141 residue near copper site in native bovine Cu,Zn-superoxide dismutase (Cu, Zn-SOD), four mononuclear copper complexes with tris(2-pyridylmethyl)amine derivatives having a hydrogen bonding site (pivalamido, neopentylamino, or amino groups) at the pyridine 6-position, [Cu(tnpa)(OH)]ClO4 (1), [cu(tapa)Cl]ClO 4 (2
Journal ArticleDOI
Efficient C-N bond formations catalyzed by a proton-exchanged montmorillonite as a heterogeneous Brønsted acid.
Ken Motokura,Nobuaki Nakagiri,Kohsuke Mori,Tomoo Mizugaki,Kohki Ebitani,Koichiro Jitsukawa,Kiyotomi Kaneda +6 more
TL;DR: The unique acidity of the proton-exchanged montmorillonite (H-mont) catalyst was found to be applicable to additional reactions: substitution of hydroxyl groups of alcohols with amides and anilines.
Journal ArticleDOI
Reactivity of hydroperoxide bound to a mononuclear non-heme iron site.
Akira Wada,Seiji Ogo,Shigenori Nagatomo,Teizo Kitagawa,Yoshihito Watanabe,Koichiro Jitsukawa,Hideki Masuda +6 more
TL;DR: Reactions of the isolated (bppa)Fe(III)-OOH (2) with various substrates (single turnover oxidations) exhibited that the iron-oxo intermediate generated by decomposition of 2 is a nucleophilic species formulated as [(H(2)bppa)(OOH)](2)-O*].
