151417-38-8 - Reference Information
| Use | 1,3, 5-tris (4-iodophenyl) benzene is an organic intermediate that can be made of 1,3, 5-Tribromobenzene and p-trimethylsilylphenoborate are prepared in two steps. It is reported that 1,3, 5-tris (4-iodophenyl) benzene can be used to design and develop high-performance optoelectronic devices, molecular recognition, lithium batteries, hydrogen storage materials and other organic molecular functional materials. Synthesis of C3 symmetric nano-polyaromatic hydrocarbons and structural units of molecular propellers. |
| preparation | using deoxytoluene and ethanol (volume ratio 3: 1) as mixed solvent, 1,3, 5-tribromobenzene (3.15g,10mmol), p-trimethylsilylphenoborate 2(7.72g,40mmol) and Pd(PPh3)4(293mg,0.24mmol)) were added to a 100mL three-mouth flask, vacuum is pumped, nitrogen is filled, and after repeated for 3 times, THF(20mL) and deoxypotassium carbonate solution (2mol/L,4.5mL) are injected with a syringe through a sealed latex tube, and the temperature is raised to 85~90 ℃. After reacting under nitrogen protection for 48 hours, the crude product is subjected to column chromatography (dichloromethane is the eluent) to obtain intermediates 1,3,5-tris (4 '-trimethylsilylphenyl) benzene 3(3.13g),IR(KBr),ν/cm-1:2950,1577,1542,1370,1248,1110,836,847,812,752. dissolve intermediate 3 in 100mL dichloromethane, slowly add iodine chloride (ICl,4.05g,25mmol) dichloromethane solution (20mL) under nitrogen protection, and finish the addition, at room temperature for 24h, the reaction liquid was washed with 5% sodium thiosulfate solution, the organic layer was separated, anhydrous MgSO4 was dried, concentrated, column chromatography (CCl4 as eluent), and 2.87g of light yellow powder 1,3, 5-tris (4-iodophenyl) benzene was recrystallized in carbon tetrachloride to obtain a yield of 42%. |
