Towards the Synthesis of o-Diphosphaquinones: Benzodiphosphadihydropentalene - Naphthodihydrodiphosphete

o-Quinodimethanes 1 are important intermediates in organic synthesis that may be generated by thermal valence isomerization of benzocyclobutenes or octa-1,2,4,6,7-pentaenes.The preparation of a stable o-quinodimethane has not been reported so far.Whereas o-quinodiimines 2 containing strongly electron-withdrawing groups at the nitrogen atoms are isolable, o-diphosphaquinones 3 have not been detected. - Keywords: Propargyl rearrangement; DBU; Electrocyclization; Diphosphaquinone; Dihydrodiphosphete
