In the ceric ammonium nitrate-initiated graft polymerization of acrylonitrile (AN) with starch, grafting frequencies and molecular weights of grafted polyacrylonitrile changed from 600 anhydroglucose units (AGU)/graft and 120000 to 280 AGU/graft and 36000 when concentrations of starch and AN were varied from 0.27 and 1.20 to 0.023 and 0,235 moles/I. of water, respectively. The influence of vari...

A series of red-shifted azobenzene amino acids were synthesized in moderate-to-excellent yields via a two-step procedure in which tyrosine derivatives were first oxidized to the corresponding quinonoidal spirolactones followed by ceric ammonium nitrate-catalyzed azo formation with the substituted phenylhydrazines. The resulting azobenzene-alanine derivatives exhibited efficient trans/cis photos...

A series of novel bis-1,3,4-oxadizaoles were synthesized by oxidative cyclisation of respective Schiff bases derived from dicarbohydrazide using ceric ammonium nitrate (CAN) as catalyst. The synthesized compounds were screened for in vitro antibacterial activity against Staphylococcus aureus (MTCC 87), Escherichia coli (MTCC 46) and antifungal activity against Candida albicans (NCIM 3471) by tw...

A novel green and efficient one-pot multicomponent reaction of dihydropyridine derivatives was reported as having good to excellent yield. In the presence of the catalyst ceric ammonium nitrate (CAN), different 1,3-diones and same starting materials as 5-bromothiophene-2-carboxaldehyde and ammonium acetate were used at room temperature under solvent-free condition for the Hantzsch pyridine synt...

A novel method for D-glucose (D-Glu) and trimethylammonium chloride immobilization onto the surface of cellulose powder was studied. Cellulose powder was grafted with vinyl monomer glycidyl methacrylate (GMA), using ceric ammonium nitrate as an initiator, and further derived with quaternary ammonium groups to build the D-GluN-type cellulose absorbent (Cell-g-GMA-D-GluN). Epoxy cellulose was fou...

In the present work, a grafted polymer of polyacrylamide with gum arabica was synthesized as Gum acacia-g-polyacrylamide using microwave-assisted synthesis ceric ammonium nitrate reaction initiator. The utilized in combination sodium alginate to prepare interpenetrating network hydrogel beads effectively deliver gabapentin gastrointestinal tract. formulated microbeads showed pH-responsive relea...
