## Abstract The reductive metallation of 6โmethylโ2,3โdiphenylquinoxaline 1 with sodium metal in tetrahydrofuran and inert atmosphere to a monomeric dianion 2 has been explored and the nucleophilicity of this disodium adduct was investigated with various alkylation and acylation reagents. An annula
## Abstract Treatment of 2,3,5,6โtetraphenylpyrazine (1) with sodium in tetrahydrofuran effected the formation of monomeric dianion 2. The chemical behaviour of this new disodium adduct was characterized by a variety of reagents. Generally, the protonation (water), alkylation (methyl iodide and ben
