Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 19959-77-4, name is 2-(5-Methyl-1H-pyrazol-3-yl)pyridine, A new synthetic method of this compound is introduced below., category: pyrazoles-derivatives
Solid ligand L (0.2mmol, 31.8mg) and Cd(NO3)2·4H2O (0.1mmol, 30.8mg) were placed into the bottom of separate arms of an H-tube. The H-tube was filled with acetonitrile solution and sealed with plastic film. After one week, colorless stick-like crystals of compound 4 were generated and collected, washed with n-hexane 2-3 times, then dried in vacuum. Yield: 42.72mg (77%), M. p. > 300C. Anal. Calc. for C18H18CdN8O6 (FW, 554.8): C, 38.97; H, 3.27; N, 20.20. Found: C, 38.31; H, 3.39; N, 19.70%. Selected IR data (cm-1, KBr): 3200 (b, s), 3135 (s), 2994 (s), 2853 (m), 2363 (s), 1607 (m) (nu(C=N)), 1578 (m) (nu(C=C)), 1435 (s), 1387 (s), 1340 (m), 1301 (m), 1225 (w), 1156 (w), 1111 (w), 1018 (w), 980 (s), 797 (s), 740 (m).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
