This article needs attention from an expert in Chemistry. The specific problem is: Lots of missing key reagents in images and incorrect/confusing (possibly "non-chemist translation engine"?) chemical terminology.(September 2019) |

1,3-Diphenylisobenzofuran is a highly reactive diene that can scavenge unstable and short-lived dienophiles in a Diels-Alder reaction. It is furthermore used as a standard reagent[6] for the determination of singlet oxygen,[7] even in biological systems.[8] Cycloadditions with 1,3-diphenylisobenzofuran and subsequent oxygen cleavage provide access to a variety of polyaromatics.
