What is the synthesis method of [Trans (trans) ] -4- (4 '-ethenyl [1,1' -bicyclohexyl] -4-yl) -1,2-difluorobenzene?

To prepare [Trans (trans) ] -4- (4 '-vinyl [1,1' -dicyclohexyl] -4-yl) -1,2-difluorobenzene, the synthesis method requires multiple delicate steps.

The first step is to find suitable starting materials to build the basic skeleton. Compounds containing dicyclohexyl can be selected, and the compound should have a modifiable check point at one end to facilitate subsequent introduction of vinyl and difluorobenzene structures.

The second step is to perform a halogenation reaction against the activity check point of dicyclohexyl compounds. The choice of halogenating agent is very critical, depending on the reaction conditions and yield. With a mild and efficient halogenating agent, the active check point is converted into a halogenated group, which is the key intermediate for subsequent reactions.

This fluorination reaction requires strict control of the reaction conditions. Temperature, catalyst and other factors will affect the fluorination position and yield. After obtaining difluorobenzene, it also needs to be properly modified to make it able to couple with halogenated dicyclohexyl intermediates. Subsequently, the halogenated dicyclohexyl intermediates are linked to the modified difluorobenzene by means of a coupling reaction. In this step, a suitable coupling catalyst, such as a palladium catalyst system, should be selected to promote the formation of carbon-carbon bonds and build the basic structure of the target molecule.

Finally, for the obtained product, if the configuration adjustment is required to achieve the [Trans (trans) ] configuration, specific isomerization reaction conditions can be used to precisely adjust, and after multiple separation and purification operations, the final result is [Trans (trans) ] -4- (4 '-vinyl [1,1' -dicyclohexyl] -4-yl) -1,2-difluorobenzene.

The melting point of similar aromatic hydrocarbons containing dicyclohexyl groups is often in the tens of degrees Celsius, and the boiling point can reach several hundred degrees. This compound may also be in this range.

Second, in terms of solubility, because it is an organic compound, it is hydrophobic, and the solubility in water is extremely low. However, because the molecule contains fluorine atoms, fluorine atoms are electronegative, or the molecule has a certain polarity, in some polar organic solvents, such as ethanol and acetone, or have a certain solubility, in non-polar organic solvents such as n-hexane and benzene, the solubility is better.

Third, the density may be similar to that of common organic compounds, slightly greater than that of water. The molecular structure of carbon, hydrogen, fluorine and other atoms is closely composed, or its unit volume mass is slightly higher. < Br >
Fourth, this material has vinyl, or has a certain chemical activity, and can undergo an addition reaction, such as with halogens, hydrogen halides and other reagents, under suitable conditions, through addition to introduce new functional groups.

However, the above are all based on their structural analogy to similar compounds. To determine its precise physical properties, experimental determination and precise analysis are required.
