The invention relates to a synthetic method of 2, 9-dinitro-4, 7-dimethyl-1, 10-phenanthroline, and belongs to the technical field of organic chemistry. The method comprises the following steps: stirring and mixing nitrobenzene and SnCl2.2H2O, filling with hydrogen, adding iron powder and hydrochloric acid, reacting under certain conditions to obtain aniline, respectively mixing aniline with hydrogen peroxide and benzoyl chloride and adding ethanol, stirring and heating, adding nitric acid, heating, adding chlorosuccinimide in a dropwise manner, mixing with a hydrochloric acid and water mixed solution, carrying out water bath heating, adding zinc powder, stirring and reacting, adding a sodium hydroxide solution, and distilling the obtained solution to obtain a distillate which is 4-methyl-8-aminoquinoline; and heating 4-methyl-8-aminoquinoline, benzoyl chloride and to reflux, cooling to room temperature, slowly adding nitric acid in a dropwise manner, filtering, mixing the obtained filtrate with stannous chloride, heating, adding zinc powder and hydrochloric acid, and carrying out stirring and pumping filtration, and carrying out vacuum drying to obtain 2, 9-dinitro-4, 7-dimethyl-1, 10-phenanthroline. The method has the advantages of mild reaction conditions, simple operation and low cost.
New nonsymmetric phenanthrolines as very effective ligands in the palladium-catalyzed carbonylation of nitrobenzene
Ferretti, Francesco,Ragaini, Fabio,Lariccia, Roberta,Gallo, Emma,Cenini, Sergio
scheme or table, p. 1465 - 1471 (2010/05/15)
Inspired by the results of a previous mechanistic study, a series of mostly new nonsymmetric phenanthrolines were synthesized and tested as ligands in the palladium-catalyzed reductive carbonylation reaction of nitrobenzene to methyl phenylcarbamate. Very good results were obtained when the asymmetry was of an electronic nature (a donating substituent in the para position of one of the two pyridinic rings and an electron-withdrawing or no substituent on the para position of the other pyridinic ring), but steric hindrance in the ortho or meta position retarded the reaction. The TOF for the modified system is the highest ever reported for any carbonylation reaction of nitroarenes.
Color responses of novel receptors for AcO- and a test paper for AcO- in pure aqueous solution
Yu, Xudong,Lin, Hai,Cai, Zunsheng,Lin, Huakuan
, p. 8615 - 8618 (2008/03/30)
An efficient AcO- sensor L which contains 1,10-phenanthroline-based and nitrophenylhydrazine-based groups, and its water-soluble Ru(II) complex were synthesized, characterized and studied in this Letter. Via UV-vis experiments and 1H NMR titration in DMSO solution, it was found that there were potential hydrogen bonds between the N{double bond, long}CH and AcO- after the deprotanation of two -NH during the reaction of L or its Ru complex with anions. Furthermore, an easy-to-prepare test paper was developed to detect AcO- at 10 mg/L in pure aqueous solution.

Synthesis of mono-and dialkylsubstituted 1,10-Phenanthrolines
Belser, Peter,Bernhard, Stefan,Guerig, Urs
, p. 2937 - 2944 (2007/10/03)
Starting from o-anisidine, alkylated 8-hydroxyquinolines 2 and 8-aminoquinolines 3 were obtained. From the latter, dialkylsubstituted 1,10-phenanthrolines 5 have been prepared in good yields. Reaction of unsubstituted 8-aminoquinoline under the same conditions, yielded monoalkylated 1,10-phenanthrolines 4.
