ABSTRACT

Oxidation of ketoximes in wet acetonitrile gives the corresponding ketones, whereas oxidationof benzaldoximes besides benzaldehyde forms benzoic acid and some 1,2,4-oxadiazoles [93].

B. Alkylated and Acylated Oximes Oximes may be alkylated at nitrogen or oxygen; both types are electrolytically reducible [I, 94,95] in their protonated form. The nitrones are generally also reducible in alkaline solution, whereas the O-methyl ethers of oximes are not reducible in ordinary media containing alkali metal ions. In solutions containing quaternary ammonium p-toluenesulfonates, some O-alkylated oximes give a polarographic wave.
