Action of isoxazol-5-ones on Schiff's bases
Abstract
3-Phenylisoxazol-5-one reacts with Schiff's bases to give substituted ammonium 4-[α-(5-hydroxy-3-phenylisoxazol-4-yl)benzyl]3-phenylisoxazol-5-olates, the cations being derived from the basic components of the Schiff's bases. Analogous salts are obtained from the action of amines on 4-arylmethylene-3-phenylisoxazol-5-ones.
