Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 39806-90-1, name is 4-Iodo-1-methyl-1H-pyrazole, This compound has unique chemical properties. The synthetic route is as follows., name: 4-Iodo-1-methyl-1H-pyrazole
General procedure: 4-Iodo-1-methyl-1H-pyrazole 1 (101 mg, 0.5 mmol) and phenylboronic 2 (59 mg, 0.5 mmol) were dissolved in DME (3 mL) and H2O (1.2 mL) in a microwave vial under a nitrogen atmosphere. Pd(PPh3)4 (2 mmol%, 11.6 mg) and Cs2CO3 (407.3 mg, 1.25 mmol) were added, and the reaction mixture was irradiated in a microwave apparatus at 90 C for 5-12 min. After the reaction mixture was cooled to ambient temperature, the product was concentrated, and the crude mixture was purified by silica gel column chromatography using petroleum ether/acetone as eluent to give the title compound.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 39806-90-1.
