Abstract
A very large quinone was prepared by the double Diels-Alder reaction of 2,5 ,9,12-tetra(t-butyl)diacenaphtho[1,2-b: 1',2'-d]thiophene and benzoquinone. The crystal structure of the polycyclic product shows that the central ant hraquinone ring system is quite twisted (50 degrees), and the overall struc ture possesses approximate D-2 symmetry.
