Hydroxyimino ethane

Benzenediamine (148) and frani-l-chloro-l,2-bis(hydroxyimino)ethane (149) gave 2(177)-quinoxalinone oxime (150), perhaps better formulated as 2-hydroxyaminoquinoxaline (151) (EtOH, 20°C, 3 h 71%) 6,7-dibromo-l,2-benzenediamine likewise gave 6,7-dibromo-2-hydroxyamino-quinoxaline. ... [Pg.24]

Bis-[hydroxyimino]-ethan (R1 = R2 = H) kondensiert mit Formaldehyd zu 1-Hydroxy-imida-zol-3-oxid und mit sich selbst zu 2-(Hydroximino-methyl)-J-hydroxy-imidazol-3-oxidZ8Z. Analog erhalt man aus l,2-Bis-[tert.-butylimino]-ethan unter Katalyse mit Chlorwasserstoff in Toluol 2-(tert.-Butylimino-methyl)-lJ-di-tert.-butyl-imidazolium-chlorid283 ... [Pg.64]
