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。
The production and application of petroleum benzene and coking benzene in China were introduced.
介绍了目前我国焦化三苯和石油三苯的生产及应用情况,并从焦化工业规模、产能地域分布等方面对焦化三苯在应用领域替代石油三苯进行了分析,可以看出,当前真正意义上的替代是在没有石化工业的山西,焦化三苯在部分地区可以替代石油三苯,但仅是三苯市场的一个适当补充,不会形成抢占市场的局面。
