Journal ArticleDOI
Searching for the second oxidant in the catalytic cycle of cytochrome P450: a theoretical investigation of the iron(III)-hydroperoxo species and its epoxidation pathways.
TL;DR: A density functional study of a model species and its ethylene epoxidation pathways concludes that iron(III)-hydroperoxo cannot be a second oxidant, in line with its significant basicity and poor electron-accepting capability.

An efficient mimic of cytochrome P-450 from a zeolite-encaged iron complex in a polymer membrane.
Rudy F. Parton,Ivo F.J. Vankelecom,Mark J. A. Casselman,Cvetana P. Bezoukhanova,Jan B. Uytterhoeven,Peter A. Jacobs +5 more
TL;DR: A composite catalytic system that achieves realistic mimicry of cytochrome P-450 as well as catalytic turnover rates that make the system industrially viable is reported, suggesting close mechanistic similarities to the enzymatic process.

Ternary Copper Complexes for Photocleavage of DNA by Red Light: Direct Evidence for Sulfur-to-Copper Charge Transfer and d-d Band Involvement
Shanta Dhar,Dulal Senapati,Puspendu K. Das,Pabitra Chattopadhyay,Munirathinam Nethaji,Akhil R. Chakravarty +5 more
TL;DR: The results indicate that the phen ligand is necessary for DNA binding of the complex, and both the sulfur-to-copper charge transfer band and copper d-d band excitations helped the DNA cleavage.

Iron-catalyzed olefin epoxidation in the presence of acetic acid: insights into the nature of the metal-based oxidant.
Rubén Mas-Ballesté,Lawrence Que +1 more
TL;DR: It is proposed that epoxidation is mediated by [(TPA)FeV(O)(OOCCH3)]2+, generated from O-O bond heterolysis of the [(T PA)FeIII(OOH)(CH3COOH)]2+ intermediate, which is promoted by the protonation of the terminal oxygen atom of the hydroperoxide by the coordinated carboxylic acid.

Alkane Oxidation with Molecular Oxygen Using a New Efficient Catalytic System: N-Hydroxyphthalimide (NHPI) Combined with Co(acac)(n)() (n = 2 or 3).
TL;DR: N-Hydroxyphthalimide (NHPI) combined with Co(acac)(n)() (n = 2 or 3) was found to be an efficient catalytic system for the aerobic oxidation of cycloalkanes and alkylbenzenes under mild conditions.
