Effective synthesis of benzyl halides triggered by in situ prepared hypervalent halides

为直接 benzylhalogenation 与的一条有效途径在 hypervalent 的 situ 产生，卤化物被开发了。许多本甲基卤化物被生产在对有高 regioselectivities 的优秀收益(多达 99%) 中等。紫外吸收光谱被采用检测 tert 丁基 hypoiodite 的形成。

An effective approach for the direct benzylhalogenation with in situ generation of hypervalent halides has been developed. A variety of benzyl halides are produced in moderate to excellent yields （up to 99%） with high regioselectivities. UV absorption spectrum is employed to detect the formation of tert-butyl hypoiodite.
