Abstract
PURPOSE: The reaction of a hypohalite with aldehyde and hydroxylamine salt gives the titled compound that is used to produce an insecticide in one-stage by no use of a large amount of base.
CONSTITUTION: A hypohalite salt is made to act on an aldehyde of formula I (R is lower alkyl) such as acetaldehyde and a hydroxylamine salt such as hydroxylamine hydrochloride to give the titled compound of formula II (X is halogen). The example of the hypohalite is sodium hypochlorite and the amount is usually 0.5W2.0mol, preferably 0.8W1.2mol/mol of the aldehyde. When the amount of the hypochlorite used is too small, the reaction does not proceed sufficiently, whereas an excessive amount undesirably causes the halogenation and oxidation of the objective product. Since the hypohalite plays roles of both neutralizer and halogenating agent in the conventional process, a large amount of base becomes unnecessary.
