The rearrangement of aldoximes to primaryamides has been studied using the readily available arene-ruthenium(II) complex [RuCl2(η6-C6Me6)P(NMe2)3}] (5 mol %) as catalyst. Reactions proceeded cleanly in pure water at 100 °C without the assistance of any cocatalyst, affording the desired amides in high yields (70–90%) after short reaction times (1–7 h). The process was operative with both aromatic

1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane dichromate (BAABCD) is a useful reagent for selective conversion of oximes and semicarbazones to the corresponding carbonyl compounds. The reaction was carried out under solventfree conditions and in the presence of a catalytic amount of aluminum chloride.

aldoximes to primary amides has been evaluated using pincer ruthenium complexes a–c, among which the ionic Ru catalyst a proved to be the most efficient in water under air atmosphere. A variety of (hetero)arene aldoximes proceeded smoothly to afford amides in high yields with good functional group compatibilities. Furthermore, a direct syntheticroute of amides from aldehydes, hydroxylamine hydrochloride
Dimethyl dithiocarbonate (DMDTC) has been shown to be an efficient dehydrating agent for a range of oximes derived from aliphatic, aromatic and heteroaromatic aldehydes yielding the corresponding nitriles in high yields.
