Ritter-Type Reactions of N-Chlorosaccharin: A method for the Electrophilic Diamination of Alkenes

摘要

N-Chlorosaccharin has been shown to undergo electrophilic Ritter-type reactions with alkenes in acetonitrile. The resulting labile β-chloro sulfonylamidines can be ring-opened and cyclized to imidazoliens. Overall this provides a one pot method for the electrophilic diamination of alkenes. Competing aziridine formation as well as allylic chlorination are also observed depending on the nature of the alkene used.
