Novel p-terphenoquinone analogues incorporating a central dihydrofurandiylidene skeleton have been synthesized. These quinones gave a stable radical cation and a stable radical anion on one-electron redox reactions showing an amphoteric property even though they do not contain any sulfur atom as an integral component. The radical cation and the radical anion of the tetra-t-butyl derivative have been characterized by EPR spectroscopy.
