1,4-Diphenylphthalazine (1) was reduced in tetrahydrofuran by sodium metal to a monomeric dianion 2.Chemical reactions of this new dianion were examined with various reagents.Generally, the protonation, acylation and alkylation products were 1,2-dihydrophthalazine derivatives.An annulation of the phthalazine ring system was accomplished by treating the dianion with 1,3-dichloropropane or 1,4-dichlorobutane.With 1,2-dichloroethane however, only 1,4-diphenylnaphthalene was detected.
