Abstract

The excellent oxidizing behavior of the μ-oxo-bridged phenyliodine trifluoroacetate 1 is revealed during the phenolic oxidations mediated by hypervalent iodine (III) reagents. The use of the μ-oxo-bridged compound 1 instead of PhI (OAc) 2 (PIDA) and PhI (OCOCF3) 2 (PIFA) during the oxidative cyclization of phenols involving carbon–oxygen, carbon– nitrogen, and carbon–carbon bond formations could produce spirocyclized ...
