通过连续反应,合并操作等途径对 Masai-Rausch 反应进行了改进,提高了烯烃收率,并扩大了合成的适用范围,使其成为某些专一几何构型三芳基乙烯的合成方法之一.用改进方法合成了一些立体专一性的三芳基乙烯,收率一般为50～70％.产物除经常规分析外,还通过钛环中间体的分离与分析、比较烯烃异构化前后的波谱变化、烯烃氧化产物的制备以及反应历程分析,确定了它们的结构.
The Masai-Rausch reaction is improved by continuous reaction and combination operation, which increases the olefin yield and enlarges the applicable range of synthesis, making it one of the synthetic methods for some specific geometry triaryl ethers. Some stereospecific triaryl ethers were synthesized by the improved method, and the yield was generally 50-70%. In addition to the routine analysis, the products were also separated and analyzed by means of titanium ring intermediates to compare the spectra before and after olefin isomerization Changes in the preparation of olefin oxidation products and reaction course analysis to determine their structure.
