Process for producing azine compounds and oxime compounds
A process comprising allowing a peroxide compound represented by following Formula (2): wherein Ra, Rb, Rc and Rd are the same or different and are each a hydrogen atom or a hydrocarbon group, and wherein Ra and Rb, Rc and Rd may be combined to form a ring together with the adjacent carbon atom, respectively, to react with ammonia and water to yield an azine compound represented by following Formula (3): wherein Ra, Rb, Rc and Rd have the same meanings as defined above, or oxime compounds represented by following Formulae (4a) and/or (4b): wherein Ra, Rb, Rc and Rd have the same meanings as defined above, in the presence of a nitrogen-containing cyclic compound constitutively having a skeleton represented by following Formula (A) in its ring: wherein X is one of an oxygen atom and an —OR group, and wherein R is one of a hydrogen atom and a hydroxyl-protecting group. This process can produce an oxime compound or an azine compound useful as a material for oxime compounds from low-cost materials by easy and simple procedures.
