These compounds can initiate anionic polymerisation of epoxides, and when R, = H the secondary amine can react by addition to an epoxide group. Farkas and Strohm 64> have studied the reaction of 2-ethyl-4-methyl imidazole with phenyl glycidyl ether and BADGE resin using chemical analysis and proton NMR spectroscopy. They found that the imidazole readily forms adducts with epoxide of 1 1 and 1 2 molecular ratio ... [Pg.126]

Suitably substituted 1,2-diamines and derivatives can by cyclized into 2H-imidazoles either by photolytic or thermal treatment in the presence of base. The 2/f-imidazole products, however, cannot always be thermally isomerized to the 1/f-isomers. The migratory aptitudes of 2-substituents have been shown to lie in the order methyl[Pg.15]

Dimethyl-3-(2-oxo-2-phenyl-ethyl--bromid lagert sich beim Kochen mit Triethylamin in Acetonitril in 2-(2-Imino-5-phenyl-2,3-dihydro-oxazol-3-yl)-4,6-dimethyl-pyrimidin um. Aus diesem werden durch Kochen in Alkoholen mit 4-Methyl-benzolsulfonsaure als Katalysator 2-Alkoxy-l-(4,6-dimethyl-2-pyrimidyl)-4-phenyl-imidazole oder durch Erhitzen mit primaren oder sekundaren Aminen ebenfalls in Gegenwart von 4-Methyl-benzolsulfonsaure 2-Alkylamino-l-(4,6-dimcthyl-2-pyrimidyl)-4-phe-nyl-imidazole erhalten374 ... [Pg.83]

Die Umlagerung von 2-Amino-5-methyl-3-(2-oxo-2-phenyl-ethyl)-1,3,4-oxadiazolium-broraid mit heiBer wiiBriger Kaliumcarbonat-Losung zu l-Acetylamino-2-hydroxy-4-phenyl-imidazol wurde bereits im Bd. X/2, S. 345 beschrieben. [Pg.87]

Wird die Ringerweiterung statt mit Bortrifluorid mit Meerwein-Reagens durchgefuhrt, so erhalt man mit Benzonitril aus 2-Methyl-3-phenyl-2H-azirin hauptsachlich l-Ethyl-2,5-diphe-nyl-4-methyl-imidazol und aus 3-Methyl-2-phenyl-2H-azirin 1-Ethyl-2,4-diphenyl-5-methyl-imidazol44°. [Pg.94]

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]

Dabei entstchcn aus 1-substituierten Imidazolen wie z.B. l-Benzyl-2-methyl- oder 1,2-Dime-thyl-imidazol unter Verbrauch von zwei Aquivalenten Benzoesaure-chlorid die 1-substituierten 2-(2-Benzoyloxy-2-phenyl-ethenyl)-imidazole wie z.B. 2-(2-Benzoyloxy-2-phenyl-etheny1)-l-benzyl- (97%) oder 2-(2-Benzoyloxy-2-phenyl-ethenyl)-l-methyl-imidazol (93%), die zu 1-Ben-zyl-2-(2-oxo-2-phenyl-ethyl)- bzw. l-Methyl-2-(2-oxo-2-phenyl-ethyl)-imidazol hydrolysiert werden konnen 766 768. [Pg.178]
