Abstract

On the other hand, gold-catalyzed organic reactions have been extensively studied recently. 5 Gold catalysts can efficiently activate alkynes, allenes, and alkenes due to their soft Lewis acidities. Nevertheless, the activation of cyclopropenes by gold catalysts has developed much less. Very recently, Shi and co-workers reported gold-catalyzed rearrangement of vinylcyclopropenes which leads to indene derivatives. 6 Lee and co-workers reported gold-catalyzed ring- ...
