# Mechanism of oxidative dearomatisation with hypervalent iodine

The following step was taken from the synthesis of Kinamycin C on SynArchive. It employs the use of a peculiar reagent, that is, bis(acetoxy)iodobenzene (BAIB), also known as phenyliodine(III) diacetate (PIDA). Being a high-valent iodine species, it is used as an oxidising agent in organic chemistry. So clearly, there is some sort of oxidation taken place in this step, along with nucleophilic aromatic substitution involving an $$\ce {MeOH}$$ molecule. However, I am quite uncertain as to what is the mechanism by which this step takes place.
