583-39-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 583-39-1, name is 2-Mercaptobenzimidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
To the solution of PdCl2(PPh3)2 (0.050 g, 0.07 mmol) dissolvedin 10 mL of CH3CN, bzimSH (0.021 g, 0.14 mmol) was added followedby Et3N base (0.5 mL). The solution became turbid and yellowishorange in color. Then the refluxing was done for 6 h. Thecolor of the reaction mixture became orange and was filtered.The filtrate was evaporated using rotary evaporator until a solidwas obtained. It was treated with acetone which dissolved thecomplex leaving behind Et3NH+Cl, white solid. The acetone solutionwas filtered to remove Et3NH+Cl. To it was added 4 mLdichloromethane-methanol (1:1, v/v) mixture and left to evaporateat room temperature. The orange colored crystals of compound2 were formed in a period of 10-15 days (67%, m.p 218-220 C). Anal. Calc. for C75H61ClN6P3Pd2S32H2O (1519.67): C,59.22; H, 4.01; N, 5.53. Found: C, 59.80; H, 4.36; N, 5.52%. IRbands(KBr, cm1): nu(O-H), 3393m (b); m(C-H), 3051m, 2963w; nu(C-C) + nu(C-N) + delta(C-H), 1618s, 1479m, 1433s, 1391s, 1263m,1226w;, 1182 w; nu(P-CPh), 1096s; nu(C-S) 1022s; 802m, 741s,691s, nu(Pd-N), 523s; 422w. ESI Mass could not be recorded dueto poor solubility.
The synthetic route of 2-Mercaptobenzimidazole has been constantly updated, and we look forward to future research findings.
