One-pot assembling of selenazolines from elemental selenium, alkenes and acetonitrile

摘要

A new method for assembling 1,3-selenazolines by the iodine mediated reaction of the simplest building blocks such as elemental selenium, alkenes and acetonitrile has been discovered. A proposed mechanism includes the addition of the intermediate selenium iodides to alkene with subsequent solvent interception by the formed seleniranium ion.
