Chemie der Nitrosamine, IV. Synthesen von α‐C‐funktionellen N‐Nitrosodialkylaminen: Ester und Ether von 1‐[(Alkyl)(nitroso)amino]alkoholen

Abstract: linine (Schiff-Basen) addieren Nitrosylchlorid unter Bildung von N-Alkyl-1-chlor-N-nitrosoalkylaminen 13. Durch nucleophile Substitution mit Acetat oder p-Nitrobenzoat sind daraus die Acetate 7 und 9 sowie dlep-Nitrobenzoate 8 und 10 zuganglich. Die spektroskopischen Daten und die chemischen Eigenschaften der neu dargestellten Verbindungen werden diskutiert.

“…Silver trifluoromethanesulfonate (AgOTf, 0.30 g, 1.16 mmol), 1-bromoadamantane ( 45 , 0.25 g, 1.16 mmol), N -ethylidene- tert -butylamine ( 46 , 0.11 g, 1.16 mmol), and methyllithium (0.75 mL, 3.10 M in diethoxymethane, 2.32 mmol) were used to prepare the title compound. The reaction mixture was extracted, worked up, and purified as mentioned in method D-1 to yield compound 43 as a pure white solid (0.12 g, 42% yield).…”

“…The known α-alkoxy- N -nitrosamines formally are the products of RO−NO addition to imines, but their actual formation is more involved . The ON−Cl addition to imines was demonstrated by Wiessler et al, and the resulting α-chloro- N -nitrosamines readily react with acetates to α-acetoxy- N -nitrosamines. The additions of HNO 2 to the cyclic imines 1 − 3 all are exothermic, and moreover, their exothermicities are so high as to overcompensate for any entropy losses and the reactions also are exergonic (Table ).…”
