An Induction Period in a Gold(I)-Catalysed 1,6-Enyne Cycloisomerisation, Traced to a Chloride-Bridged Digold Reservoir
A paper from the School of Underlying Conditions follows a gold(I)-catalysed enyne rearrangement by in situ ¹H and ³¹P NMR and traces its 38-minute induction period to a chloride-bridged digold cation, which holds 93% of the gold at 30 min and turns over about seventy times more slowly than the free cation. The lag ends when a slowly dissolving silver salt has abstracted half the chloride; grinding the salt shortens it to 16 min, and a catalyst premixed and filtered before use shows none.
