Photochemistry of Aromatic Nitro Compounds, XVIII. – Photolysis of 2,6‐Di‐tert‐bytl‐1‐nitronaphthalene
While o‐nitro‐tert‐butylbenzenes 1 generally undergo a light‐induced cyclization to 3H‐indole 1‐oxides 4 or products derived therefrom, the benzohomologous 2,6‐di‐tert‐butyl‐2‐nitro‐naphthalene (5) upon irradiation exclusively forms the binaphthylidene quinone 10; the 2‐tert‐butyl group remains unaffected during the photolysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
