[Figure not available: see fulltext.] The main objective of this work was to study the rearrangement reactions of 1-alkyl-2-[(phenylsulfonyl)methyl]pyridinium iodides in the presence of various nucleophiles, leading to N-alkyl-2-(phenylsulfonyl)aniline derivatives. The best results were achieved with alkylammonium sulfites, leading to pyridine ring opening followed by recyclization to give diphenyl sulfone derivatives in up to 78% yields.
Electron beam-induced fries rearrangement of sulfonamide and sulfonate crystals
Kato, Jun,Maekawa, Yasunari,Yoshida, Masaru
, p. 266 - 267 (2007/10/03)
The electron beam (EB) sensitivity of sulfonic acid derivatives in the crystalline state was much higher than that of the corresponding carboxylic acid derivatives, which was distinct from the results using other energy sources such as heat and UV; especially, sulfonamide derivatives could undergo the chemoselective Fries rearrangement to give ortho and para products in the ratio of ca. 7/3 without the meta isomer.
