To better understand the effect of thioether coordination in copper-O(2) chemistry, the tetradentate N(3)S ligand L(ASM) (2-(methylthio)-N,N-bis((pyridin-2-yl)methyl)benzenamine) and related alkylether ligand L(EOE) (2-ethoxy-N,N-bis((pyridin-2-yl)methyl)ethanamine) have been studied. The corresponding copper(I) complexes, [(L(ASM))Cu(I)](+) (1a) and [(L(EOE))Cu(I)](+) (3a), were studied as were the
Inspired by β-CD, a macrocyclic oligomers of D-(+)-glucopyranose and a renewable material, which could be obtained from starch, that can promote a lot of organic reactions in water, a green solvent, several amino alcohol-modified β-CDs CD-1 to CD-7 were synthesized

The mechanism of sulfoxidation of thioaniosoles by a non-heme iron(IV)-oxo complex is switched from direct oxygen transfer to metal ion-coupled electron transfer by the presence of Sc(3+). The switch in the sulfoxidation mechanism is dependent on the one-electron oxidation potentials
Two new artificial hemoproteins or "hemozymes", obtained by non covalent insertion of Fe(III)-meso-tetra-p-carboxy- and -p-sulfonato-phenylporphyrin into xylanase A from Streptomyces lividans, were characterized by UV-visible spectroscopy and molecular modeling studies, and were found to catalyze the chemo- and stereoselective oxidation
