An air‐stable cationic Au I complex featuring a Z‐type ligand (boron atom) as a σ‐acceptor was developed for elucidating the effect of B on catalytic reactions. An enyne cyclization in the presence of either [Au→B] + or [Au] + showed that [Au→B] + promotes the reactivity, which enabled the effective construction of not only five‐ and six‐membered rings, but also seven‐membered rings.
