Die Oxidation der Schiffschen Basen (I) mit tert.‐Amylhydroperoxid in Gegenwart der Molybdänverbindungen (II) oder (III) führt zu den Oxaziridinen (IV) (66 ‐ 95%).
268ChemInform Abstract The arylhydrazones (I) react with the dialkyl phosphites (II) to give the α-hydrazinophosphonates (III). The bisphosphonate (V) is obtained from the Schiff base (IV) and (IIa) in a similar manner, whereas the aliphatic Schiff base (VI) gives the αα-bis(phosphoryl)methyl compound (VII). The enamine (IX) is treated with (IIa), producing (VIIa). The bisthiophosphonate (XIII) is synthesized from (XI) and (XII). (IR-, 31P-NMR-data).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
