Nature of the intermediates in gold(I)-catalyzed cyclizations of 1,5-enynes

The carbene or carbocationic nature of the intermediates in the gold-catalyzed cycloisomerization of 1,5-enynes can be revealed, depending on the ligands on the gold catalysts. Gold complexes with highly electron-donating ligands promote reactions that proceed via intermediates with carbene-like character, leading to products with a bicyclo[3.1.0]hexene skeleton. The intermediate cyclopropyl endo-gold carbenes formed in this cyclization have been trapped, for the first time, to give biscyclopropane derivatives in a reaction that proceeds in a concerted fashion, according to DFT calculations.

Gold-catalyzed reactions of 1,5- and 1,6-enynes with carbonyl compounds: cycloaddition vs. metathesis

Gold-catalyzed reactions of 1,5- and 1,6-enynes with carbonyl compounds was demonstrated. It was observed that 1,n-enynes (n = 5-7) achieved skeletal rearrangement in the presence of a variety of electrophilic metals as catalysts, where-as in the presence
