Both the Au and the carbene ligand are essential for the reaction to occur, as removal of either gives no desired carboxylation product. Finally, the fact that the reaction proceeds at ambient ...

The unique reactivity of gold complexes as tunable p-Lewis acids have driven diverse applications towards C–C multiple bond functionalizations, enyne and diyne cycloisomerizations, carbene/nitrene ...

The cyclization event is initiated by an enyne cyclization — classified as 5-exo-dig using Baldwin's notation — leading to a cyclopropyl gold carbene. A rapid intramolecular reaction with the ...
