Wu, Qian published the artcileUnified synthesis of mono/bis-arylated phenols via RhIII-catalyzed dehydrogenative coupling, Application In Synthesis of 209919-30-2, the publication is Chemical Science (2017), 8(1), 169-173, database is CAplus and MEDLINE.
A general strategy that allowed for the precise control of the oxidation pathways so that directing groups can be either preserved or cleaved was reported. It was found that N-phenoxyacetamides underwent ortho-arylation reactions with or without an external oxidant, yielding products with different oxidation states, notably the rare bis-arylated phenols. Notably, a unique rhodacycle intermediate was isolated, characterized by X-ray crystallog. and confirmed to be an active catalyst. Switching between internal and external oxidation could be a general strategy in diverse directed C-H functionalization reactions to realize bis-functionalized products.
