The invention provides a bipyridine derivative useful as an intermediate for pharmaceutical products, agricultural chemicals, electrophotographic photosensitive materials, dyes and the like, which is a bipyridine derivative represented by the general formula (I) and a salt thereof:
wherein R1 represents an alkyl group with 2 to 20 carbon atoms having a substituent, substituted or unsubstituted aminomethyl group, trifluoromethyl group, substituted or unsubstituted thiomethyl group, substituted or unsubstituted alkenyl group, substituted or unsubstituted alkoxy group, substituted or unsubstituted aryloxy group, substituted carbonyl group, substituted sulfonyl group, unsubstituted or monosubstituted carbamoyl group, unsubstituted or monosubstituted sulfamoyl group, substituted or unsubstituted thiol group, unsubstituted or monosubstituted amino group, substituted carbonylamino group, substituted or unsubstituted ureido group, nitro group, cyano group, formyl group or an equivalent thereof, iodine atom or fluorine atom.
该发明提供了一种对制药产品、农药化学品、电子感光材料、染料等具有中间体作用的双吡啶衍生物,其为一种由通式(I)表示的双吡啶衍生物及其盐:其中R1代表具有取代基的2至20个碳原子的烷基基团,取代或未取代氨甲基基团,三氟甲基基团,取代或未取代硫甲基基团,取代或未取代烯基基团,取代或未取代烷氧基团,取代或未取代芳氧基团,取代羰基团,取代磺酰基团,未取代或单取代的氨甲酰基团,未取代或单取代的磺酰胺基团,取代或未取代硫醇基团,未取代或单取代的氨基团,取代羰基氨基团,取代或未取代脲基团,硝基基团,氰基团,甲酰基团或其等效物,碘原子或氟原子。
