Abstract
Abstract Reaction of hydroxylamine hydrochloride with aryl trifluoromethyl-β-diketones affords 5-hydroxy-5-trifluoromethyl-Δ 2 -isoxazolines rather than the reported 3-trifluoromethylisoxazoles. The structural assignment is based on the analysis of their NMR ( 1 H, 13 C and 19 F) spectral data and of their dehydration products, 5-trifluoromethylisoxazoles.
