3.4- Dicyan-2-phenyl

Bei der Diazotierung von 2-Amino-4,5-dicyan-imidazol erhalt man das exploslonsgefahrliche 2-Diazoniono-4,5-dicyan-imidazolat, das z. B. mit Benzol zu 4,5-Dicyan-2-phenyl-imidazol und mit 1,2-Dichlor-ethan zu 2-Chlor-l-(2-chlor-ethyl)-4,5-dicyan-imidazol umgesetzt werden kann993. [Pg.170]

Durch Kondensation von 2-Phenyl-2-oxo-acethydroximsaure-chlorid und Benzamidin-Hydro-chlorid erhalt man 2,4(5)-Diphenyl-5(4)-nitroso-imidazol (s.Bd. X/l, S. 1071). 2,2-Dicyan-3-phenyl-oxiran reagiert mil Amidinen unter Abspaltung von Benzaldehyd zu 4-Amino-5-cyan-imidazol115. Ein Beispiel fur diese Reaktion ist die U msetzung mit N-Phenyl -benzamidin zu 4-Amino-5-cyan-1,2-diphenyl-imidazol (80%) ... [Pg.33]

Nitro-arenc mil stark aktivierter Nitro-Gruppe reagieren mit Nitro-anilinen oder Amino-benzonitrilen zu Diphenylaminen, z.B. zu (2-Nitro-phenyl)-(4-nitro-phenyl)-amin (65-70%) oder (2,4-Dicyan-pkenyl)-(4-cyan-pkenyl)-amin (80%)1. [Pg.755]

Bis-[dicyan-methylen]-2-fluoro-EI0b,. 247 (NII2 -> F) 5-(Bis-[peniafluoro-phenyl]-meihy-len)-3-oxo-tetrafluoro- E10b2. [Pg.767]

The reaction of epoxide resins with dicyanates was investigated using a model system. The system consisted of phenyl glycidyl ether and cumylphenyl cyanate [67]. Three reactions proceeded in the system ... [Pg.49]
