Halodiazirines as Valuable Reagents for the Synthesis of Halocyclo­propanes

Abstract

AbstractHalodiazirines have emerged as very useful reagents in photochemically or thermally mediated cyclopropanation reactions with alkenes. This short review highlights the synthetic applications of these reagents as precursors of halocarbenes in transformations with various alkenes.1 Introduction2 Cyclopropanation of Aryl Halodiazirines3 Tandem Reactions Using Aryl Halodiazirines4 Cyclopropanation of Alkyl- and Benzyl-halodiazirines5 Cyclopropanation of Other Halodiazirines6 Reactions of Halodiazirines with Alkynes7 Conclusion and Outlook
