With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.787-70-2,[1,1′-Biphenyl]-4,4′-dicarboxylic acid,as a common compound, the synthetic route is as follows.
787-70-2, General procedure: A mixture of Eu(NO3)3¡¤6H2O (0.089 g,0.2 mmol), Na2L (0.112 g, 0.2 mmol), 1,10-phenanthroline¡¤H2O (0.04 g, 0.2 mmol), 4,4?-biphenyldicarboxylic acid (0.05 g, 0.2 mmol), one drop triethylamine and H2O(15.0 ml) in a 25 ml Teflon-lined autoclave was heated at 150 C for 33 h. After the mixture was cooled slowly to ambient temperature, yellow block crystals were obtained. The crystalswere filtered,washedwith distilledwater and dried at ambient temperature. The yield of the reaction,determined fromtheweight of the solvent-free material (0.138 g), is 71.5% based on Na2L. Anal. Calcd (%) for C47H32O8N2S2Eu: C,58.27; H, 3.33; N, 2.89. Found: C, 58.22; H, 3.42; N, 2.95. IR data (KBr pellet,upsilon/cm-1): 3062 (m), 3021 (m), 2668 (m), 2551 (m), 1685 (s), 1598 (s), 1417 (s),1252 (s), 760 (s), 607 (s). The procedure for preparing 2-4 is similar to that for 1,but the reaction temperature is 170 C rather than 150 C (see Supporting Information2).
787-70-2 [1,1′-Biphenyl]-4,4′-dicarboxylic acid 13084, acatalyst-ligand compound, is more and more widely used in various fields.
