p-Ethyl-phenylacetylene was synthesized from starting materials ethylbenzene via five steps by acylation、reduction、dehydration、bromize、eliminition reaction.And the conditions were optimized. 以乙苯作为原料,通过乙酰化、还原、脱水、溴化和消除五步反应合成了乙基苯乙炔,并对反应条件进行了优化。
Phenylacetylene is an alkyne hydrocarbon containing a phenyl group. It exists as a colorless, viscous liquid. In research, it is sometimes used as an analog for acetylene; being a liquid, it is easier to handle than acetylene gas.
