Isobenzofuran is a chemical compound from the group of bicyclic heteroaromatics and is the oxygen analog of isoindole . It is made up of a furan ring and a fused benzene ring. It is isomeric to benzofuran .

Appearance and properties

Isobenzofuran is much more unstable than benzofuran due to its electronic configuration. It can be formed by vacuum pyrolysis of benzo [ b ] -7-oxa-bicyclo [2.2.1] hept-2-ene and polymerizes rapidly even at low temperatures. The compound is the basic structure of some other natural and man-made organic compounds, of which the 1,3- diaryl- substituted (such as 1,3-diphenylisobenzofuran ) are the most stable.
