Acid-catalysed Isomerization of Indol-3-yl Sulphides to Indol-2-yl Sulphides: Unexpected Intermolecular Nature of the Rearrangement
Hamel, Pierre,Girard, Yves,Atkinson, Joseph G.
, p. 63 - 65 (1989)
The rearrangement of indol-3-yl sulphides (1) indol-2-yl sulphides (4), catalysed by proton acids, unexpectedly proceeds by an intermolecular mechanism involving initial disproportionation to an indole-2,3-diyl bis-sulphide (2) and an indole (3), followed by a reaction between (2) and (3) to yield the rearranged product (4).
