Aromatic Diazonium Salts, IX. The Nα, Nβ-Interchange in Aromatic Diazonium Salts during SolvolysisThe Nα, Nβ-interchange during the solvolysis of [β-15N]benzenediazonium tetrafluoroborate in 2,2,2-trifluoroethanol under N2 was inhibited by less than 4% when the free radical inhibitors bromotrichloromethane, 1,1-diphenylethylene or methyl acrylate were added. Under an air atmosphere the N-inversion was increased by 8%. The main part of the N-inversion under solvolysis conditions is therefore not occurring via reversible addition of phenyl radicals to the diazonium salt.
Notes:
Der Nα, Nβ-Austausch in [β-15N] Benzoldiazonium-tetrafluoroborat bei der Solvolyse in 2,2,2-Trifluorethanol unter N2 wurde durch Zusatz der Radikalinhibitoren Bromtrichlormethan, 1,1-Diphenylethylen und Acrylsäure-methylester nur um maximal 4% erniedrigt. Unter Luftatmosphäre stieg die N-Inversion um 8% an. Eine umkehrbare Addition von Phenyl-Radikalen an das Diazoniumsalz ist daher als Hauptweg der N-Inversion unter Solvolysebedingungen ausgeschlossen.
