Microwave-assisted synthesis of N-hydroxyphthalimide derivatives
N-Hydroxyphthalimide derivatives are readily obtained in good yields by the reaction of phthalic anhydrides with hydroxylamine hydrochloride in the presence of pyridine under microwave irradiation.

Mild and convenient one pot synthesis of N-hydroxyimides from N-unsubstituted imides
A new, one pot synthesis of various N-hydroxyimides from N-unsubstituted imides is described. Imides are first transformed into their N-Boc derivatives, which are next reacted with aqueous hydroxylamine, providing crystalline hydroxylammonium salts of the corresponding N-hydroxyimides. Filtration and acidic workup affords pure N-hydroxyimides.

N-hydroxyphthalimide/cobalt(II) catalyzed low temperature benzylic oxidation using molecular oxygen
A variety of (substituted) aryl glyoxylates is formed in good to excellent yield under very mild conditions by direct oxidation of the corresponding arylacetic esters or mandelic acid esters with molecular oxygen and N-hydroxyphthalimide/cobalt(II) acetate as catalyst. Heteroaromatic analogs are more difficult to oxidize with this system. The effect of substitution in the aromatic ring of N-hydroxyphthalimide on the oxidation of ethylbenzene has been studied. Electron withdrawing substituents accelerate the oxidation of ethylbenzene and promote the formation of acetophenone. Electron donating substituents lead to decreased rates of oxidation and enhance the selectivity for 1-phenylethanol. (C) 2000 Elsevier Science Ltd.
