Study of the oxidation of 2-aminophenol by molecular oxygen catalyzed by cobalt(II) phthalocyaninetetrasodiumsulfonate in water

Oxidation of 2-aminophenol with molecular oxygen and hydrogen peroxide catalyzed by water soluble metalloporphyrins

“…The oxidative coupling of 2-aminophenol (OAP) to 2-amino-3H-phenoxazine-3-one (APX) through catalytic activation of dioxygen by transition metal complexes (Scheme 1) has been considered as one of the important reactions [4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The enzyme phenoxazinone synthase is involved in the last stages of the biosynthesis of actinomycin D, a naturally occurring antibiotic, which is used clinically for the treatment of Wilm's tumor, gestational choriocarcinoma and other tumors [18][19][20].…”

“…Cobalt salts [8], cobalt(II) salen [9,10] bis-(dimethyl-glyoximato) cobalt(II) complexes [11] and cobalt(II) phthalocyanine derivatives [12,13] have been used as catalysts for the oxidative coupling of OAP. TEMPO (2,2,6,6-tetramethyl-1-pipridinloxyl) initiated oxidation of OAP has been reported by Speier and co-workers [14].…”

A Waste-Free and Highly Effective Catalytic System for the Oxidation of Cysteine to Cystine

“…It is well-known that molecular oxygen can be catalytically activated by transition metal phthalocyanine complexes [11][12][13][14][15][16][17]. However, the parent metal phthalocyanine complexes are less soluble in water and common organic solvents, which limit their application in catalysis [18].…”

The Surface Modification of the Polypropylene by Aqueous Soluble CoII Phthalocyanine to Obtain Materials for Catalysis

“…[2,[6][7][8][9][10][11] However, there is a significant drawback of using these compounds -propensity to self-association in solution. [12][13][14] Processes of self-association of metal phthalocyanines in aqueous and nonaqueous media affect their catalytic properties ambiguously.…”
