Diazomethane umpolung atop anthracene: an electrophilic methylene transfer reagent

Formal addition of diazomethane's terminal nitrogen atom to the 9,10-positions of anthracene yields H(2)CN(2)A (1, A = C(14)H(10) or anthracene). The synthesis of this hydrazone is reported from Carpino's hydrazine H(2)N(2)A through treatment with paraformaldehyde. Compound 1 has been foun...
