Direct functionalization of C-H bonds catalyzed by chloroperoxidase (CPO) is featured by using H2O2 as both oxygen and electron donor. The catalytic process circumvents expensive electron transporters such as NAD(P)H, making it advantageous for green production of fine chems. with complex structures. In situ generation and collaborative supplement of H2O2 is strongly desired for an improved productivity and enzyme stability. The present study describes a novel CPO cascade for asym. hydroxylation of ethylbenzene yielding (R)-1-phenylethanol, in which H2O2 is generated by oxidation of monosaccharides catalyzed by gold nanoclusters (AuNCs). A core-shell structure of CPO-AuNCs cascade was prepared by using hollow mesoporous silica microspheres (HMSMs) as the support. AuNCs were immobilized on the external surface of HMSMs while CPOs were encapsulated inside the microspheres. Different monosaccharides were examined for H2O2 production as a function of the particle size. It was found that galactose exhibits the highest productivity. The high compatibility of CPO and AuNCs against temperature and pH is advantageous in catalyzing a wide spectrum of reactions for C-H functionalization. The experimental process involved the reaction of ABTS Diammonium(cas: 30931-67-0COA of Formula: C18H24N6O6S4)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. Examples of direct uses of amines and their salts are as corrosion inhibitors in boilers and in lubricating oils (morpholine), as antioxidants for rubber and roofing asphalt (diarylamines), as stabilizers for cellulose nitrate explosives (diphenylamine), as protectants against damage from gamma radiation (diarylamines), as developers in photography (aromatic diamines), as flotation agents in mining, as anticling and waterproofing agents for textiles, as fabric softeners, in paper coating, and for solubilizing herbicides.COA of Formula: C18H24N6O6S4
