Abstract: This paper reports a new oxidant--NH4CrO3Cl(ACC) which is the most inexpensive oxi-dant in oxochromium (Ⅵ)--amine oxidants and can be prepared easily.ACCis able to oxidate selectively active carbon-hydrogen bonds in carbonyl compounds, benzylic compounds and fused ring aromatic hydrocarbons.It is an efficient reagent with which the α-methyl or α-methylene groups in carbonyl compounds can be oxidized selectively into corresponding 1,2-dicarbonyl compounds by using ACC.The cycloketone can be oxidized into α, β-cyclic enone with a high efficiency; the benzylic methylene groups into benzylic ketones with good yield; and the fused ring aromatic hydrocarbons into quinones with a moderate yield.

Key words: Selective oxidation, Selective oxidant, Ketone, Quinone, 1,2-Dicarbonyl compound
