The synthesis method of 1% 2C2% 2C4% 2C5-tetraene-3- (trienomethyl) benzene often involves the category of organic chemistry. To make this product, one can think of the following ways.
First, use benzene derivatives as starting materials. Select a benzene compound with a specific substituent, and introduce an alkenyl-containing group by means of an electrophilic substitution reaction. For example, if the starting benzene ring has a suitable positioning group, the electrophilic reagent can be reacted at the specified position. Using halogenated olefins as electrophilic reagents, with the help of catalysts such as Lewis acid, and reacting with benzene derivatives, through steps such as addition and elimination, it is expected to introduce alkenyl groups at specific positions in the benzene ring.

Second, consider the strategy of building a carbon-carbon bond. Reactions such as Grignard reagents can be used. First prepare alkenyl-containing halogenated hydrocarbons, make Grignard reagents, and then react with carbonyl-containing benzene derivatives. This reaction can increase the carbon chain and introduce alkenyl fragments. Subsequent reactions such as dehydration and rearrangement adjust the molecular structure and approach the target product. This process requires attention to the preparation conditions of Grignard's reagent to ensure that its activity is appropriate, and the connection of subsequent reaction steps also needs to be carefully planned to prevent side reactions.
Third, the coupling reaction catalyzed by metal is used. Such as Suzuki reaction, Heck reaction, etc. Select suitable halogenated aromatics and alkenyl boric acid (ester) compounds, and under the action of catalysts and ligands such as metal palladium, a coupling reaction occurs. Such reactions have good selectivity and atomic economy, and can effectively construct carbon-carbon double bond structures.
