What are the physical properties of 4- [ (3,3,4,4,4,5,5,6,6,7,7,8,8-trifluorooctyl) thio] butane-1-mercaptan

This question is to explore the physical properties of 4- [ (3,3,4,4,5,5,6,6,7,7,8,8-tridecanoamino) borane] -potassium-1-boronic acid. This compound is characterized by both borane and potassium salts.

The structure of borane often has unique electronic properties, and its boron atoms tend to be electron-deficient, making the compound highly reactive. The introduction of tridecanoamino groups may increase the hydrophobicity of molecules due to the influence of long-chain alkyl groups. Long-chain alkyl groups such as tridecanes have weak polarity, which decreases the solubility of molecules in polar solvents and increases the solubility in non-polar or weakly polar organic solvents.

Potassium ions give the compound salt properties and can be ionized in suitable solvents. This may make the compound have a certain ionic conductivity, which has potential applications in electrolyte-related fields.

The boric acid part is weakly acidic and can give protons under appropriate conditions. This acidity may affect the stability and reactivity of the compound in different pH environments.

What is the synthesis method of 4- [ (3,3,4,4,5,5,6,6,7,7,8,8-trifluorooctyl) thio] butane-1-mercaptan

To obtain 4 - [ (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8 - tridecyl benzyl) silyl] acetylene - 1 - silica ether synthesis method can be as follows.

First take an appropriate amount of (3, 3, 4, 4, 5, 6, 6, 7, 7, 8, 8 - tridecyl benzyl) halides, under the protection of inert gas, add an appropriate amount of silyl acetylene metal salts, such as lithium silyl acetylene or sodium silyl acetylene, etc., in a suitable solvent, such as anhydrous tetrahydrofuran, etc., and stir the reaction at a controlled temperature. This reaction should pay attention to changes in temperature, and should not be too high or too low to prevent side reactions. After a period of reaction, confirm the progress of the reaction by thin layer chromatography or other suitable monitoring means.

When the reaction reaches the desired level, the reaction solution is post-treated. The reaction can be quenched with an appropriate amount of dilute acid solution, and then extracted with organic solvents, such as dichloromethane, ethyl acetate, etc. The organic phases are combined, dried with a desiccant such as anhydrous sodium sulfate, filtered to remove the desiccant, and the solvent is removed by reduced pressure distillation to obtain a preliminary crude product.

Then the crude product is purified. Column chromatography can be used to select suitable silica gel and eluent, such as a mixed solvent of petroleum ether and ethyl acetate. After elution, a suitable fraction is collected, and the solvent is removed by reduced pressure distillation again. A relatively pure 4 - [ (3, 3, 4, 4, 5, 5, 6, 7, 8, 8 - tridecyl benzyl) silyl] acetylene can be obtained.

Then take this product, and a suitable silicon etherification reagent, under the catalysis of alkali, such as potassium carbonate, triethylamine and other bases, in an organic solvent, such as acetonitrile, etc., stir the reaction. The reaction process also needs to be closely monitored. After the reaction is completed, the post-treatment method is similar to before. After extraction, drying, distillation and other steps, the final product can be 4- [ (3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8 - tridecylbenzyl) silyl] acetylene-1 - silicone ether. Each step requires fine operation and attention to the control of reaction conditions to improve the yield and purity.
