Adding a certain compound to certain chemical reactions, such as: 455-13-0, name is 4-Iodobenzotrifluoride, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 455-13-0, Computed Properties of C7H4F3I
Add in a 50 mL autoclave, add 5 mL of toluene, 1 mmol of 4-trifluoromethyliodobenzene, 1.2 mmol of phenylacetylene, 2.0 mmol of triethylamine, 0.5 mol% of benzimidazole, azacyclocarbene palladium Metal complex (relative to iodobenzene).The reactor was sealed, and the reactor was replaced three times with carbon monoxide to seal the reactor. The pressure of the CO gas was 2.0 MPa, and the temperature was slowly raised to 100 C by the temperature controller. The reaction was carried out for 18 hours, cooled to room temperature, and the kettle was discharged. The liquid obtained by the reaction was qualitatively analyzed by an Agilent 6890/5973 GC/MS.Target product1-(4-trifluoromethylphenyl)-3-phenyl-2-propyn-1-oneThe selectivity is greater than 99% and the isolated yield is 95%.
