Crystallographic evidence for unintended benziso­thia­zolinone 1-oxide formation from benzo­thia­zinones through oxidation

摘要

X-ray crystallography revealed the unintended formation of benziso­thia­zolinone 1-oxides from 1,3-benzo­thia­zin-4-ones through oxidation instead of the anti­cipated benzo­thia­zinone sulfones, which would be constitutional isomers.
