Rapid Spectrophotometric Determination of Phenoxazine
مجلة بغداد للعلوم, 2010 A rapid high sensitive and inexpensive economic method has been developed for the Determination of phenoxazine by using molecular spectrophotometry. The method is based on the oxidation of phenoxazine by potassium (meta)periodate in acidic medium.

Metal-free formal synthesis of phenoxazine [PDF]
Beilstein Journal of Organic Chemistry, 2018 A transition metal-free formal synthesis of phenoxazine is presented. The key step of the sequence is a high-yielding O-arylation of a phenol with an unsymmetrical diaryliodonium salt to provide an ortho-disubstituted diaryl ether.

Nickel-Catalyzed cine-Substitution Toward Carbonyl Dance. [PDF]
Chem Asian JA nickel‐catalyzed cine‐substitution enables a 1,2‐carbonyl translocation (“carbonyl dance”) at tetralone derivatives under mild conditions. This transformation proceeds through enolization and selective amination, followed by hydrolysis, to afford β‐tetralones bearing migrated carbonyl groups.

Enhanced Microbial Sensing via Resazurin Reduction Catalyzed by Graphene Oxide, A Versatile Approach for Diagnostics and Electrochemical Applications. [PDF]
Environ ToxicolABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

New Functionalized Phenoxazines and Phenothiazines
ACS Omega, 2023 The reaction of either 2-aminophenol or 2-(N-methylamino)phenol with 1,2-difluoro-4,5-dinitrobenzene and sodium carbonate in EtOH gives 2,3-dinitrophenoxazines. One nitro group, conjugated to the aryl ether, was displaced from 2,3-dinitro-10-methylphenoxazine with different nucleophiles: BuNH2, KOEt, and KOH.

Highly Efficient Candlelight Organic Light-Emitting Diode with a Very Low Color Temperature
Molecules, 2021 Low color temperature candlelight organic light-emitting diodes (LEDs) are human and environmentally friendly because of the absence of blue emission that might suppress at night the secretion of melatonin and damage retina upon long exposure. Herein, we
