摘要: Publisher Summary This chapter discusses the synthesis, transformation, and decomposition of three-membered rings. The reviews three classes compounds—(1) oxaziridines, (2) diaziridines, (3) diazirines. configurational stability, reactions, photochemical formation, transformation oxaziridines are described in chapter. application new oxidizing reagents has led to procedures oxaziridine synthesis. Alkyl hydroperoxides presence catalytic amounts molybdenum compounds, reagent Halcon epoxidation, makes from Schiff bases good yield. Simple reactions such as their behavior toward acids, bases, ferrous salts reviewed describes synthesis diaziridines. two compounds diaziridines—diaziridinones diaziridinimines also discussed. preparation diazirines, diazoalkane interconversion, thermal photolytic Fluorodiazirines that diazirines described, which obtained suitable perfluorinated amines by reduction with ferrocene or iodide, well diphenylamine, semicarbazide, hydrochloride, electrolytic reduction.
