1,3-Benzoxazol

Benzoxazole reagieren unter nitrierenden Bedingungen zu Mono- oder Dinitro-2,1-benzoxazolen. 6-Nitro-2,l-benzoxazol jedoch bildet unter Ringspaltung Bis-[2-carboxy-3,5-dinitro-phenyl -diazen-l-oxidl[i6% Schmp. 225° (Zers.)]1 ... [Pg.131]

Unter ahnlichen Bedingungen werden 1,2- und 1,3-Oxazolc zu 3- bzw. 2-Amino-alko-holen gespalten, z. B. 2,1-Benzoxazol zu 2-Amino-benzylalkohol (65%)2 ... [Pg.1024]

Benzoxazole werden mit verschiedenen Reagenzien unter Ringoffnung zu substituier-ten Benzolen umgesetzt. Mit Triphenylphosphan erhalt man beim Erhitzen in Toluol Tri-phenylphosphan-2-acyl-phenylimideb53-, z.B. ... [Pg.102]

Es wird angenommen, daB 2,1-Benzoxazol eine nitrenartige Form im Gleichgewicht bildet, die durch das tert.Phosphan abgefangen wird653. [Pg.102]
