TL;DR: In most cases, products having similar structural frameworks were obtained through alkyne activation with Brønsted acids, iodine and gold complexes; the difference is whether H or I is incorporated in the final products; however, in a few cases, different reactivities and product structures were observed between those three reagents and catalysts.

TL;DR: The SEM and TEM characterization of nanoporosity show that the AuNPore catalyst has a bicontinuous 3D structure and a high density of atomic steps and kinks on ligament surfaces, which should be one of the important origins of catalytic activity.

TL;DR: In this article, the [3+2] cycloaddition between various nitriles and trimethylsilyl azide proceeds smoothly in the presence of a Cu I catalyst in DMF/MeOH, to give the corresponding 5-substituted 1 H -tetrazoles in good to high yields.

TL;DR: The synthesis of triazoles via the three-component coupling reaction of unactivated terminal alkynes, allyl carbonate, and trimethylsiyl azide under the Pd(0)-Cu(I) bimetallic catalyst is developed.

TL;DR: In this article, the [3+2] cycloaddition of nonactivated terminal alkynes and trimethylsilyl azide has been shown to yield N-unsubstituted triazoles in good to high yields.
