The generation of substituted gamma-lactones can be accomplished through application of a tandem chain extension-aldol reaction, followed by CAN-mediated oxidative cleavage of the aldol product. The oxidative cleavage requires the intermediacy of a hemiketal and the presence of an alpha-heteroatom.

The direct conversion of alpha-hydroxy ketones and alpha-keto oximes into quinoxaline derivatives in the presence of a catalytic amount of ceric ammonium nitrate via metal-catalyzed aerobic oxidation followed by in situ trapping with aromatic 1,2-diamines in water as a green
The ceric ammonium nitrate promoted oxidations of 4,5-diphenyloxazoles and oxazoles with various substitution patterns have been investigated. This transformation results in the formation of the corresponding imide in good yield and tolerates a wide variety of functional groups and substituents

A series of Cp*Ir complexes can catalyze C-H oxidation, with ceric ammonium nitrate as the terminal oxidant and water as the source of oxygen. Remarkably the hydroxylation of cis-decalin and 1,4-dimethylcyclohexane proceeds with retention of stereochemistry. With H(2)O(18), cis-decalin oxidation

The high-power ultrasonic irradiation of preformed magnetite (Fe(3)O(4)) nanoparticles in the presence of monoelectronic Ce-containing ceric ammonium nitrate [Ce(IV)(NH(4))(2)(NO(3))(6)] oxidant in MeCOMe afforded hydrophilic 50 nm-sized colloidal, highly stable maghemite (gamma-Fe(2)O(3)) nanoparticles. An "inorganic" Ce atom doping of the NP
