Dicobaltoctacarbonyl-mediated deoximation

Treatment of oxime O-acetates with Co2(CO)8 in the presence of a base, followed by H2O at room temperature efficiently afforded the parent carbonyl compounds in high yields. Direct regeneration of carbonyl functionalities from the corresponding oxime derivatives was realized by successive exposure to acetylation conditions, Co2(CO)8 in the presence of base, and H2O. In addition, N-monosubstituted hydrazone derivatives could generate the parent carbonyl compound under the above conditions.

The one-pot conversion of primary and secondary alcohols into phenylhydrazones and 2,4-dintrophenylhydrazones is reported using chromium trioxide supported on silica gel and phenylhydrazines or 2,4- dintrophenylhydrazines under solvent-free conditions. This oxidation arylhydrazone formation reaction has been applied to a range of aliphatic and benzylic alcohols. Copyright Taylor & Francis, Inc.
H2SO4/SiO2 as an efficient catalyst for the preparation of phenylhydrazones and 2,4-dinitrophenylhydrazones under solvent-free conditions

, p. 569 - 573 (2007/10/03)
H2SO4 mixed with silica gel (1:1) by weight produces a white powder which is an effective catalyst for the conversion of carbonyl compounds to their corresponding phenylhydrazones and 2,4-dintrophenylhydrazones under solvent-free conditions.
