摘要: Ring opening of dibenzo-1,2-oxathiin 2-oxide (1a) and 3,4-dihydro-1,2-benzoxathiin (1b) is accelerated by buffer bases while that 3H-2,1-benzoxathiole 1-oxide (1d) essentially independent concentrations in tertiary amine buffers or decelerated some buffers. These results are taken as evidence for the hypervalent intermediate this reaction.
