Application of Salicylaldehyde

CN201811305638.0 discloses a method for preparing liquid crystal materials, which belongs to the technical field of liquid crystal materials. The raw materials o-ethylaniline and o-hydroxybenzaldehyde used in the present invention are both cheap and easy to obtain, wherein o-ethylaniline is brominated through the protection of acetyl groups , Suzuki coupling, deprotection, diazotization, halogenation, lithiation and boration to obtain the intermediate biphenylboronic acid; at the same time, o-Hydroxybenzaldehyde undergoes bromination, Williamson etherification reaction, Wittig reaction, hydroboration? oxidation reaction to obtain the intermediate Bromobenzene containing alcohol ether, biphenylboronic acid and bromobenzene containing alcohol ether were subjected to Suzuki coupling, ester formation and deprotection to obtain the final liquid crystal material. The solvent used in the present invention is relatively environment-friendly, easy to operate and has few risk factors, the Suzuki coupling reaction does not produce coupling impurities produced by multi-substituted halogenated products, and the single-step reaction has high selectivity. The invention adopts convergent route design, the total yield can reach more than 40%, the cost is low, and the economic benefit is good.
