The synthesis of triphenylmethyl substituted olefin via Witting reaction;
用Witting反应合成三苯甲基取代烯烃
Six olefins bearing triphenylmethyl group were synthesized.
合成了6种三苯甲基取代烯烃。
In this paper, we synthesized four triphenylmethyl substituted olefins——the 3,3,3-triphenylpropene is synthesized by elimination reaction;the 4,4,4-triophenylbut-1-ene and 5,5,5-triphenylpent-1-ene are prepared through couple reaction; and the 2-methyl-5,5,5-triphen-ylpent-2-ene is obtained by wittig reaction.
三苯甲基衍生物在理论研究，高分子和医药等方面都有较多的应用。
