The counterion effect in the gold(I)-catalyzed dearomative condensation of indoles with allenamides is unveiled by means of 1D- and 2D- NMR investigation. The different coordination ability and hydrogen bonding tendency of TFA− and OTf− led to specific interactions with the reaction partners dictating the regiodivergent outcome.

Abstract

The counterion effect in the gold(I)-catalyzed dearomative condensation of indoles with allenamides is unveiled by means of 1D- and 2D- NMR investigation. The different coordination ability and hydrogen bonding tendency of TFA− and OTf− led to specific interactions with the reaction partners dictating the regiodivergent outcome.
