Abstract

Significant localization of the unpaired electron on the phosphorus atom of phosphasemiquinone radical anion 1·^- was revealed by EPR species was generated by reduction of 1, the first stable p-phosphaquinone. Employment of the 3,5-di-tert-butyl-4-oxocyclohexa-2,5-dien-1-ylidene moiety was essential for the synthesis as well as the effective kinetic protection of 1.
