The ketoximes by the action of acetyl chloride undergo a peculiar inframolecular re-arrangement known as the Beckmann trans formation (E.
Ketoximes are usually rather more difficult to prepare than aldoximes, and generally require the presence of a fairly concentrated alkaline solution.
In order to arrive at the configuration of the stereoisomeric ketoximes, A.
Piloty, Ber., 1902, 35, p. 3 0 93); and by the action of nitrogen peroxide on ethereal solutions of ketoximes (R.
On oxidation with chromic acid they yield dinitrohydrocarbons, and on reduction with hydroxylamine (in alkaline solution) or with potassium sulphydrate give ketoximes, RR': C: NOH (R.
