摘要: Abstract The action of phenylhydrazine and hydroxylamine hydrochloride on the o-hydroxychalcones (Ia b) yields pyrazoline iso-oxazoline derivatives (IIa b; IIIa respectively. primary aliphatic amines IIa b affords 2-acetyl-1-naphthol N-alkylimines (Va-c). Ia–d react with paraformaldehyde, yielding quantitatively 3,3′-diacyl-4,4′-dihydroxydinapthylmethane IVa–d. IR NMR spectra products are discussed.
