Über die Oxydation sekundärer Amine mit Wasserstoffperoxid. 23. Mitt. über Hydroxylamin‐Derivate

Abstract: Entgegen Literaturangabem laBt sich Dimethylamin mit Wasserstoffperoxid ohne Katalysatoren zu N-Hydroxy-dimethylamin oxydieren; mit dcm gleichfalls entatehenden Formddehyd bildet sich N-Hydroxymethoxy-dimethylamin, welches ale l,l-Diphenyl-5,5-dimethyl-dihydro-1,2,4,5-boradioxazol identifiziert werden kann. Das 2: 1-Addukt von Dicyclohexylamin und Waaeerstoffperoxid bildet auch ohne Katalysatoren ein 1 : 1-Addukt von Dicyclohexylamin und Cyclohexanonoxim . Weiter wird uber die Oxydation von Diisopropylamin und… Show more

“…The addition products, originally regarded as N-hydroxymethyloxydialkylamines (4) by Zinner and Ritter (1,2), react with diphenylboron-supplying reagents (Ph,B-X) to yield crystalline compounds which were initially assigned the structure 5 containing intramolecular N -+ B coordination. This assignment was based on the earlier studies of the "boroxazolidines" by Weidmann and co-workers (3)(4)(5) and was subsequently employed for compounds of this type (6)(7)(8)(9)(10).…”

“…2,3-Dihydro-4H-pyran (24 g, 0.28 mol) was added in portions and the temperature was kept below 40 8C. After complete addition and stirring for another 10 min, the mixture was poured into H 2 O containing NaHCO 3 (10 mmol (354); Typical Procedure: [526] CAUTION: 1,2-Dibromoethane is an eye, skin, and respiratory tract irritant and is a probable human carcinogen.
