Elaboration on the Electronics of Salen Manganese Nitrides: Investigations into Alkoxy-Substituted Ligand Scaffolds
The ligand electronics of salen manganese nitride complexes directly influence the locus of oxidation and, thus, the reactivity of the resulting oxidized species. This work investigates the influence of tert-butoxy, isopropoxy, and methoxy substituents on

Enantioselective epoxidation of cyclic 1,3-dienes catalyzed by a sterically and electronically optimized (salen)Mn complex
Chiral (salen)Mn(III)Cl complexes catalyze epoxidation of cyclic 1,3-dienes with moderate-to-good enantioselectivity. A new catalyst (2), bearing sterically hindered and electron donating (OSi(iPr)3 (OTIPS) substituents, induces up to 12% higher selectivity than the previously-reported tert-butyl substituted analog 1.

An Electron Spin Resonance Study of Radicals produced by Oxidation of ortho-Mono- and -Di-hydroxybiphenyls
The e.s.r. spectra obtained by oxidation of biphenyl-2,2'-diols in neutral solution showed the formation of a monoaryloxyl radical in which the unpaired electron is shared equally by both rings.In the spectra of radicals from unhindered 2,2'-diols variati

Oxidation of Alkoxyphenols. Part 27. The Mechanism of Formation of Dibenzodioxepins
Electron spin resonance, kinetic evidence, and product isolation show that in the oxidation of 4-methoxy-3-t-butylphenol one of the initial products is 2-(4-methoxy-3-t-butylphenoxy)-4-methoxy-5-t-butylphenol.The radical of this compound reacts with anoth
