99% | In water;Reflux; | Example 1 Synthesis and Characterization of 7,8-dihydroxy-phenazine-2-sulfonic acid (0105) 7,8-dihydroxy-phenazine-2-sulfonic acid (DHPS) was synthesized in one step from refluxing a mixture of <strong>[7474-78-4]3,4-diaminobenzene sulfonic acid</strong> and 2,5-dihydroxy-1 ,4-benzoquinone (see Scheme 1 supra). While both starting materials are available at modest prices from commercial suppliers, both are also derived in straightforward syntheses from the bulk commodity chemicals 1 ,2-phenylenediamine and 1 ,4- dihydroxybenzene, respectively, making the reported material scalable at low cost. A round bottomed flask was filled with 130 ml_ of water and began warming to 105 °C in an oil bath. While warming, solid 2,5- dihydroxy-1 ,4-benzoquinone (8.278 g., 0.059 mol) was added to the reaction flask. Then, over a 5 minute period, solid <strong>[7474-78-4]3,4-diaminobenzenesulfonic acid</strong> (1 1 .106 g., 0.059 mol) was added to the reaction mixture. After refluxing overnight the reaction mixture was cooled to room temperature, diluted with 150 ml_ of acetone, and then filtered to yield a gold solid which was washed with water and then acetone. The solid was dried under vacuum for 6 days to yield the product (17.063 g., 99percent). 1 H-NMR (500 MHz, DMSO-afe) delta: 8.25 (s, 1 H), 8.09 (d, J = 8.5 Hz, 1 H), 8.01 (d, J = 8.5 Hz, 1 H), 7.33 (s, 1 H), 7.32 (s, 1 H). The acidic proton could not be located due to exchange with residual water in the DMSO-afe. 13C-NMR (125 MHz, DMSO-afe): 156.2, 155.6, 148.8, 141 .0, 140.1 , 138.5, 137.0, 127.5, 126.8, 1 21 .9, 1 06.0, 105.2. MS (ES ) m/z: 291 (M - H)-. UV-vis (1 M NaOH) lambda (epsilon / M-1 cm 1): 267 (48900), 297 (31800), 434 (231 00). |

In methanol; for 0.5h; | The solid HB-CTcomplex was prepared by dissolving equimolar amounts(0.5 mmol) of AMMP and DHBQ in MeOH (25 mL). theAMMP solution was added to the DHBQ solution, and themixture was stirred for 30 min. then, the solvent wasallowed to evaporate at room temperature. the HB-CTcomplex was obtained as a dark-pink solid product, whichwas Dltered and washed with MeOH. 'e CHN contents andphysical data of the solid complex are given in Table 1, wherethe analytical calculations confirmed that the HB-CTcomplex was formed as [(AMMP)2(DHBQ)]. |
