摘　　要：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.An effective approach for the direct benzylhalogenation with in situ generation of hypervalent halides has been developed.
