73.6% | With dmap; 2-chloro-1-methyl-pyridinium iodide; In N,N-dimethyl-formamide; at 100.0℃; for 3.0h; | A mixture of zinc(II) complex of 5-(4-aminophenyl)-10,15,20-triphenylporphyrin (0.10g, 0.14mmol), 2,2?-bipyridine-4-carboxylic acid (Hetcat, Switzerland) (0.037g, 0.18mmol), 2-chloro-1-methylpyridinium iodide (0.14g, 0.53mmol) and 4-dimethylaminopyridine (0.17g, 1.4mmol) in DMF (10cm3) was heated at 100C for 3h. The solvent was evaporated, and the residue was dissolved in dichloromethane (10cm3) and washed three times with water (10cm3). The material obtained was purified by column chromatography (silica gel) using dichloromethane containing 5% methanol as an eluent. The compound obtained was recrystallized from the mixture of chloroform and n-hexane. The yield was 73.6%. The purity of the product was checked with 1H NMR and elemental analysis.

To a solution of 32 mL of methanol and 8 mL of a saturated aqueous solution of NaHCO3, 0.165 g (0.82 mmol) of 2,2?-bipyridine-4-carboxylic acid is added and heated to 50 C. until the solution is clear. Then 0.4 g (0.82 mmol) of cis-dichlorobis(2,2?-bipyridine)ruthenium(II) (Ru(bipy)2Cl2.2H2O) are added and the mixture is refluxed for 24 h. After cooling in an ice bath for 1 h conc. H2SO4 is added dropwise to adjust the solution to pH 3. The formed precipitate was filtered washed with MeOH, the filtrate was treated with 5 g NaPF6 in 25 ml H2O, then cooled in an ice bath, and the precipitate was collected by filtration |

78.15% | With cobalt(II) diacetate; glacial acetic acid; butanone at 20℃; Large scale; | 1-6 Example 6 At room temperature, 4-methyl-2,2'-bipyridine (2kg, 1.0eq), cobalt acetate (416.0g, 0.2eq), 2-butanone (200mL), and acetic acid (8L) were added in sequence to high and low temperature In the jacketed reactor, oxygen was introduced, and the temperature was raised to reflux overnight. After the reaction was completed, it was cooled to room temperature and concentrated. The residue was diluted with 4 L of water, adjusted to pH=910 with 40% sodium hydroxide solution, and filtered. Remove insolubles, first wash the filtrate with 4L of dichloromethane, then separate the water phase, adjust the pH of the water phase to 5-6 with 4mol/L hydrochloric acid solution, filter, and recrystallize the filter cake with methanol to obtain 1.84 kg of 4-formic acid -2,2'-bipyridine (white solid), molar yield 78.15%, HPLC purity 99.5%. |
