Title: Manufacture of bipyridylium salts
Inventor: COLCHESTER JOHN EDWARD
IPC: C07D213/22
Filed: 1968-12-23
Abstract: 1,259,840. Bipyridylium salts. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 Nov., 1969 [23 Dec., 1968], No. 61010/68. Heading C2C. 1,1<SP>1</SP> - Disubstituted - 4,4<SP>1</SP> - bipyridylium salts are obtained by treating the corresponding 1,1<SP>1</SP> - disubstituted - 1,1<SP>1</SP>,4,4<SP>1</SP> - tetrahydro- 4,4<SP>1</SP> - bipyridyl with an organic compound which has a redox potential in water more positive than-1À48 volts as compared with the saturated calomel electrode and which accepts a hydride ion to form an anion which under the reaction conditions has a redox potential more negative than - 0À45 volt as compared with the saturated calomel electrode, and subsequently oxidizing the resulting 1,1<SP>1</SP>-disubstituted-1,1<SP>1</SP>-dihydro- 4,4<SP>1</SP>-bipyridyl by means of an oxidizing agent which has a redox potential in water more positive than -0À50 volt as compared with the standard calomel electrode. Preferably the reaction is carried out in an organic solvent which dissolves the starting bipyridyl and the oxidizing agent. The preferred starting bipyridyls are those carrying alkyl or carbamidoalkyl groups on the nitrogen atoms. The bipyridyls may carry further substituents in the 2-, 3-, 5- and 6-positions, e.g. alkyl groups. Suitable oxidizing agents are, for example, ceric sulphate; metal salts, especially halides; inorganic oxyacid anhydrides, especially sulphur dioxide and sulphur trioxide; air or oxygen in conjunction with water, carbon dioxide and/or acetic acid; or organic oxidizing agents, for example, benzoquinone, chloroanil and anthraquinone. The salts may be recovered from the reaction mixture by conventional processes, e.g. by extraction with water or a dilute acid, e.g. sulphuric, hydrochloric, phosphoric or acetic acid, the salt being extracted from the aqueous phase so obtained by evaporation and crystallization.
