Abstract

The 1,1,2,2‐bis(1,3‐diketo‐2,2‐bindanylidene)ethane radical anion (13) and 1,1,4,4‐bis (1,3‐diketo‐2,2‐binanylidene)butene‐2 radical anion (14)We employ herein nomenclature wherein the term ‘radical anion’ means the gain of one electron of the named substrate.

representing 1,6‐ and 1,8‐conjugated semidiones have been prepared by reduction. Electron spin resonance hyperfine splitting constants have been assigned on the basis of Hückel and McLachlan calculations.
