Can α-sultone exist as a chemical species? First experimental implication for intermediacy of α-sultone
Abstract
The treatment of 2,4,6-trimethylpyridine N-oxide 8 with BnSO2Cl and Et3N in the presence of various olefins afforded unexpected γ-sultones 10 along with 2,4,6-trimethylpyridine 9, via the possible generation and/or intermediacy of an α-sultone 2 as a new reactive intermediate.
