The Synthesis of 7-t-Butylisobenzofuran-4,5-dione

Abstract

The title compound has been prepared by a route in which the key step is the decarbonylation and subsequent Alder- Rickert cleavage of the adduct between 8-t-butyl-1,4-dihydro-1,4 epoxynaphthalene-5,6-dione and tetraphenylcyclopentadienone.
