Abstract

Abstract: The up-and sp-3, 5-dimethyl-2-(9-fluorenyl) phenyl azides (4ap and 4sp) have been obtained separately from the corresponding amines 6ap and 6sp which in turn were obtained as a mixture by the AICl,-catalyzed isomerization of N-(9-fluorenyl)-3, 5-xylidine and separated by chromatography. Isomerization 4ap-4sp was studied at 40-69" C to give the kinetic and thermodynamic parameters: 4H*= 22.5 kcal/mol, 4S*=-7.6 eu, 4Gt30,,= ...
