European Journal of Organic Chemistry, Volume 29, Issue 18, 14 May 2026.A manifold of catalytic reaction paths can operate in the Au(I)‐catalyzed heteroannulation of salicylic amides and alkynes. However, a subtle initial nucleophilic advantage of N versus O and a kinetic bottleneck at an advanced stage of the mechanistic machinery seems to suffice for the reaction to run on a single path and with exquisite selectivity.

4-[4-(4-Amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazol-3-yl]-1,2,5-oxadiazol-3-amine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 The complete molecule of the compound, C(6)H(4)N(8)O(3), is generated by a crystallographic twofold rotation axis that runs through the central ring. The flanking ring is twisted by 20.2 (1)° with respect to the central ring. One of the amino H atoms forms an intra-molecular N-H⋯N hydrogen bond; adjacent mol-ecules are linked by N-H⋯N hydrogen bonds ...
