Abstract

An oxidative amination of allenes using a single hypervalent iodine reagent proceeds very efficiently for monosubstituted allenes and leads to formation of the corresponding propargylic amines, either as the internal or as the terminal amine depending on the addition of triphenylphosphine oxide to the iodine(III) reagent.
