Oxidations with IBX:benzyl halides to carbonyl compounds,and the one-pot conversion of olefins to 1,2-diketones

摘要

A variety of benzyl halides were converted to the corresponding aldehydes/ketones in respectable yields by IBX in DMSO at 65 deg C.The bromohydrin reaction of olefins using NBS-H_2O in DMSO can be nicely adapted to IBX-mediated oxidation of benz-yl halides in such a way that olefins are converted to the corresponding 1,2-diketones in good isolated yields in one-pot.
