Abstractmagnified imageDimerization of N‐protected propargylic amines in a rather rare head‐to‐tail mode has been achieved under mild conditions with high selectivity using rhodium catalysts. The N‐protecting group could be a sulfonyl, carbamate, or carbonyl functionality and (cyclooctadiene)rhodium chloride dimer/1,1′‐bis(diphenylphosphino)ferrocene {[Rh(COD)Cl]2/dppf} as well as tris(triphenylphosphine)rhodium chloride [Rh(PPh3)3Cl] proved to be active catalysts. In addition, these functionalized gem‐enynes subsequently undergo selective gold(III)‐catalyzed intramolecular hydroamination to give trisubstituted pyrroles under mild conditions.

is observed in the cyclization of propargylicamides catalyzed by bis(pyridyl)silver(I) complexes, with an unexpected reversal of electronic demand to the analogous NH addition reaction. The catalyst was found to be effective for internal alkyne substrates, offering exclusive selectivity for the 5-exo-dig product. Differences in selectivity profile between gold- and silver-catalyzed processes are highlighted
