Gold‐tinted: A gold catalyzed cyclization reaction of 1,6‐diyne‐4‐en‐3‐ols, incorporating an in situ stannyl transfer reaction involving 2‐tributylstannylfuran, gives synthetically valuable 2‐stannylnaphthalenes (see scheme; DCE=dichloroethane). A gem‐diaurated furan complex, was isolated and fully characterized by X‐ray crystallographic analysis, and provides strong evidence for a tin to gold transmetalation
