Reactions of Cyclobutenediones, XXIV. On the Reaction of 2-Hydroxy-1-phenyl-1-cyclobuten-3.4-dione with AminesPrimary aromatic amines react with 2-hydroxy-1-phenyl-1-cyclobuten-3.4-dione (1) to give the 3-arylamino-1-phenyl-cyclobutenediylium-2.4-diolates 17-27. Under the same conditions aliphatic amines, aminopyridines and amidines afford the ammonium salts 2-16, 38-43, 44-46 respectively, 1-amino-1-cyclohexen-3-one on the contrary gives the imonium salt 49. - The properties of the novel compounds are described, their structure is confirmed by means of spectroscopic measurements. The connection between ammonium salts of 1 and cyclobutenediylium-diolates is shown.
Notes:
Primäre aromatische Amine reagieren mit 2-Hydroxy-1-phenyl-cyclobuten-(1)-dion-(3.4) (1) unter Bildung der 3-Arylamino-1-phenyl-cyclobutendiylium-2.4-diolate 17-27. Unter gleichen Bedingungen liefern aliphatische Amine, Aminopyridine und Amidine die Ammoniumsalze 2-16, 38-43, 44-46, 1-Amino-cyclohexen-(1)-on-(3) hingegen das Imoniumsalz 49. - Die Eigenschaften der neuartigen Verbindungen werden beschrieben, ihre Struktur wird auf spektroskopischem Wege gesichert. Der Zusammenhang zwischen Ammoniumsalzen von 1 und Cyclobutendiylium-diolaten wird aufgezeigt.
