## OMS Letters Dear Sir ## Evidence of a Thermal Beckmann Type Rearrangement of (2-Acetyloxy4methoxyphenyl)-Zthienyl Methanone Oxime Acetates in Mass Spectrometry During our investigations of the synthesis of 6-methoxy-3-(2'-thieny1)-1 ,2-benzisoxazole,' we have prepared a new intermediate comp
## Abstract The formation and the destruction of an intermediate involved in the Beckmann rearrangement of 2,4,6βtrimethylacetophenone oxime have been studied in concentrated trifluoromethanesulfonic acid by kinetic and spectroscopic measurements. Observed (__k__~obs~) and thermodynamic rate consta
