Related Products of 61881-19-4, A common heterocyclic compound, 61881-19-4, name is 2,2,2-Trifluoro-N-phenylacetimidoyl chloride, molecular formula is C8H5ClF3N, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: Add sodium acetate, trifluoroethylimidyl chloride (II), hydrazone (III), and 1 mL of organic solvent to the 35 mL Schlenk tube according to the raw material ratio in Table 1.Mix and stir well. After the reaction is completed according to the reaction conditions in Table 2, 2-4 hours,Add elemental iodine, continue the reaction for 1-2 hours, filter, and stir the sample in silica gel.After purification by column chromatography, the corresponding 5-trifluoromethyl-substituted 1,2,4-triazole compound (I) is obtained. The reaction process is shown by the following formula:
The synthetic route of 61881-19-4 has been constantly updated, and we look forward to future research findings.
