, p. 329 - 350 (2007/10/03)
Reaction of vinylic organometallic derivatives with N-sulfinyl arenamines 2 affords the title sulfinamides 3. On heating their solutions in selected solvents to 80-124 °C, these sulfinamides are converted into the corresponding indoles 6, probably via a [3.3]-sigmatropic rearrangement to intermediates VIII which undergo an intramolecular carbophilic reaction of the nitrogen atom with the neighboring sulfine group, followed by elimination of HSOH. The triethyloxonium tetrafluoroborate- or boron trifluoride etherate catalyzed conversion 3 → 6 can be carried out at a much lower temperature. Elsevier,.

, p. 837 - 840 (2007/10/02)
Reactions of 1-alkenylmagnesium bromides with N-sulphinyl-benzenamines affords the title sulphinamides 5.On heating in toluene, these sulphonamides 5 are the transformed into the corresponding indoles.
