General Method for the Synthesis of New 1,3-Selenazolines from Elemental Selenium, Alkenes, and Nitriles
摘要
Abstract
The strategy of the synthesis of 1,3-selenazolines by the iodine-mediated reaction of elemental selenium, alkenes and acetonitrile is extended to dienes and other nitriles, and new selenazolines are obtained. Only one of the two double bonds in dienes is involved in the selenazoline ring formation. Benzo- or butyronitriles enter the reaction only when using ethyl acetate as a co-solvent.
