Direct n.m.r. detection of an epoxyfuran intermediate in peracid oxidation of the fungicide methfuroxam
Abstract
A 4,5-epoxyfuran intermediate has been detected by 1H and 13C n.m.r. spectroscopy in the oxidative conversion of 2,4,5-trimethyl-N-phenylfuran-3-carboxamide (the fungicide Methfuroxam) into 3-(N-phenylcarbamoyl)-4-methylhex-3-ene-2,5-dione.
