✦ Synopsis

Contributions to the Chemistry of Tetraketones, II. — Reaction of 3,4‐Dibenzoyl‐2,5‐hexanedione with Hydroxylamine

By treatment of 3,4‐dibenzoyl‐2,5‐hexanedione (1) with hydroxylamine (pH ≈︁ 8) 3‐benzoyl‐1‐hydroxy‐2‐methyl‐5‐phenyl‐1__H__‐pyrrole (2), 1‐hydroxy‐3,4‐bis[(hydroxyimino)(phenyl) methyl]‐2,5‐dimethyl‐1__H__‐pyrrole (3), and dimethyldiphenyl‐4,4′‐biisoxazoles as a mixture of isomers 4a and 4b were isolated from the reaction mixture. The compounds have been characterized by IR, ^1^H NMR, and mass spectra.
