The Chinese name of this compound is 1-ethoxy-2,3-difluoro-4 - [ [( trans, trans) - 4 '-propyl [1,1' -bicyclohexyl] -4-yl] methoxy] benzene. Its chemical structure is described in the style of ancient Chinese:
The structure of this compound is first based on a phenyl ring. On the phenyl ring, the first position is connected to an ethoxy group, which is in the form of a branch attached to the ring. If the ethoxy group is attached, it is formed by connecting the ethyl group to the oxygen group. The second position and the third position are each connected to a fluorine atom. Fluorine, a sexually active element, is attached to the ring and affects the properties of this compound.
Looking at the fourth position of the benzene ring, there is a rather complex group connected. This group starts as a methoxy group, which is connected to an oxygen group in methyl group, and then the oxygen of the methoxy group is connected to [ (trans, trans) -4 '-propyl [1,1' -cyclohexyl] -4-yl]. The so-called [1,1 '-cyclohexyl] is that two cyclohexyl groups are connected, one of which is carbon and the other is carbon, forming the shape of a double ring. The 4' 'position of this double ring structure is connected to a propyl group, and the propyl group is a three-carbon straight-chain alkyl group. And this double-ring structure exhibits the opposite configuration, that is, the spatial orientation of the relevant groups on the double-ring is specific, thus constituting the unique chemical structure of this compound.

It is a colorless and transparent liquid at room temperature, clear and free of impurities, and this state is convenient for its flow and application in a specific environment.
When it comes to melting point, it is finely determined and located in a specific temperature range. This temperature characteristic makes the substance undergo solid-liquid phase transformation under corresponding conditions, which has a great impact on its storage and processing. If the temperature is lower than the melting point, it is in a solid state and the structure is relatively stable; if it is higher than the melting point, it will turn into a liquid state and the molecular motion will intensify.
The boiling point is also a key physical property. When the external pressure reaches a certain standard value, the substance will boil and transform into a gaseous state. The value of the boiling point reflects its volatility. The boiling point of this substance may have a specific range. According to this, it can be known that its physical state changes under different temperature environments. This property is widely used in industrial distillation, purification and other processes.

The synthesis of 1-ethoxy-2,3-difluoro-4 - [ [ ( trans, trans) - 4 '-propyl [1,1' -dicyclohexyl] -4-yl] methoxy] benzene is an important issue in the field of organic synthesis. Its synthesis often requires multi-step reactions, and the target molecular structure is constructed with delicate strategies.
The choice of starting materials is crucial, and benzene ring derivatives with suitable substituents are often selected because they can provide the reaction basis framework. If a specific substituted anisole-like compound is used as the starting point, its methoxy group can be appropriately converted in subsequent reactions to become the 4 - [ [ ( trans, trans) - 4 '-propyl [1,1' -dicyclohexyl] - 4-yl] methoxy] moiety of the target molecule.
To introduce a 2,3-difluoro group, a fluorine-containing reagent, such as a nucleophilic fluorination reagent, can be used. Under suitable reaction conditions, a specific position of the benzene ring is fluorinated. This step requires fine control of reaction conditions, such as temperature, solvent and catalyst, to ensure fluorination reaction selectivity and yield. For example, at low temperatures and in specific organic solvents, catalyzed by a specific metal catalyst, fluorinated reagents can be promoted to attack the designated position of the benzene ring nucleophilic, and fluorine atoms can be precisely introduced.

Usually, it is necessary to prepare (trans, trans) -4 '-propyl [1,1' -dicyclohexyl] -4-alcohol first, and obtain the desired configuration alcohol through propylation and stereochemical control of dicyclohexyl derivatives. Subsequently, this alcohol is reacted with phenyl ring derivatives that already contain fluorine and ethoxy groups through Williamson ether synthesis, etc., under basic conditions, the alcohol is reacted with halogenated benzene derivatives to form a target ether bond, thereby constructing a complete molecular structure. After the
reaction is completed, the product needs to be isolated and purified, and column chromatography, recrystallization and other means are used to obtain high purity 1-ethoxy-2,3-difluoro-4 - [ [ ( trans, trans) - 4 '-propyl [1,1' -dicyclohexyl] - 4 '-yl] methoxy] benzene.
