Matsumoto, Kazuhiro,Kato, Miyako,Sakamoto, Takeshi,Kikugawa, Yasuo

, p. 34 - 35 (2007/10/03)

Treatment of N-aryl-N-methoxyacetamides, which bear a strong electron-donating group on the aryl ring, with an AlCl3-Me2S system results in heterocyclic cleavage of the nitrogen-oxygen bond and introduction of a methylsulfanyl group at the ortho or para position of the aryl ring.
