α‐Allenols were catalytically transformed into dihydrofurans in the presence of platinum dichloride. Notably, using platinum dichloride along with silver triflate as the catalytic system, α,β‐unsaturated ketones were obtained. Therefore, the role of the silver salt may not just consist in the activation of the platinum precatalyst.
在二氯化铂存在下,将α-烯丙醇催化转化为二氢呋喃。值得注意的是,使用二氯化铂和三氟甲磺酸银作为催化体系,可制得α,β-不饱和酮。因此,银盐的作用可能不仅在于铂预催化剂的活化。
