Manganese(II) chloride (0.075 mmol, 10 mg), dipyridylacetylene(0.075 mmol, 14 mg) and biphenyl-4,4?-dicarboxylic acid (0.075 mmol, 18 mg) were suspendedin a mixture of dimethylformamide (8 mL), water (1 mL)and ethanol (1 mL) in a glass autoclave. The closed vesselwas then heated at 110 C over a period of 3 days. Then,the mixture was allowed to cool to rt in a rate of 5 C h-1,whereupon long needles formed which were filtered offand subjected to single crystal X-ray diffraction. Yield:14 mg (58%); dec. < 379 C. As the paragraph descriping shows that 787-70-2 is playing an increasingly important role. Reference£º

To a stirred solution of biphenyl-4,4′-dicarboxylic acid (500 mg, 2.06 mmol) in 10 mL of DMF was added N-hydroxysuccinimide (594 mg, 5.16 mmol) and dicyclohexylcarbodiimide (1.06 g, 5.16 mmol) at 0C and the mixture stirred at RT overnight. The reaction mixture was filtered and the filtered cake was washed with EtOAc. The washings and filtrate were combined, washed with brine solution (3×20 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford a crude product that was dissolved in DCM and again filtered. The DCM layer was concentrated under reduced pressure to afford desired product (600 mg).
