Phthalic anhydride - Wikipedia
Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics.

Isobenzofuran - Wikipedia
Isobenzofuran is a bicyclic heterocycle consisting of fused cyclohexa-1,3-diene and furan rings. It is isomeric with benzofuran. Isobenzofuran is highly reactive and rapidly polymerizes; however, it has been identified [2] and prepared by thermolysis of suitable precursors and trapped at low temperature. [3]
