has been developed for the construction of synthetically important tri-substituted tetrahydrofuran derivatives from bromo-alkenes and bromo-alkynes by radical cyclization reactions using the radical initiator Cp2TiCl, generated in situ from commercially available titanocene dichloride and Zn dust in tetrahydrofuran under argon.
已经开发了一种新颖有效的方法,用于使用自由基引发剂Cp 2 TiCl通过自由基环化反应从溴代烯烃和溴代炔烃中构建合成重要的三取代四氢呋喃衍生物,该自由基引发剂是由可商购的二茂钛二氯化物和Zn粉尘原位生成的在氩气中于四氢呋喃中。
