ARYLSULFENYLATION OF 2,3-DIALKYLINDOLES; PREPARATION OF 3-ARYLTHIOINDOLENINES AND THERMAL CONVERSION TO AN N-SULFENYLINDOLE

Dmitrienko, Gary I.,Friesen, Richard W.,Carson, Loraine,Vice, Susan F.

, p. 821 - 824 (1982)

Reaction of 2,3-dialkylindoles with o-nitrophenylsulfenyl chloride in the presence of triethylamine gives good yields of previously unknown 3-o-nitrophenylsulfenyl-2,3-dialkylindolenines which decompose thermally to give the corresponding 2,3-dialkylindole and N1-o-nitrophenylsulfenyl indoles.
