I am attempting to synthesis benzene with the ortho amines with the sulfo groups on the opposite side to increase water solubility. Once made it will be reacted through a condensation reaction will phendione (1,10-phenanthroline-5,6-dione) to form a dppz (dipyridophenazine) ligand that has the the sulfo group on the opposite end of the phenanthroline. Thus far my attempts were reacting 2-nitro-5-chloroaniline with dimethylamine in DMF with potassium carbonate, NMR resulted in an unexpected spectra, indicating side reactions. However ei-ms indicated the correct product. Upon reduction attempts of the product (desired 2-nitro-5-dimethylaniline) apparently the reaction is extremely air sensitive.
