摘要: Mechanistic investigation of gold(I)-catalyzed intramolecular allene hydroalkoxylation established a mechanism involving rapid and reversible C–O bond formation followed by turnover-limiting protodeauration from mono(gold) vinyl complex. This on-cycle pathway competes with catalyst aggregation an off-cycle bis(gold)
