, p. 895 - 900 (2007/10/02)
The equilibrium constants for complexation of a diazonium cation with a crown ether, as determined from kinetic data on azo coupling with aromatic amines, increase with decreasing polarity of the solvent, indicating a predominant contribution of electrost
Mechanism of Diazo Coupling Reactions. Part XXXII. The Diazoamino Rearrangement in 20percent Acetonitrile/Aqueous Buffers
Kelly, Richard P.,Penton, John R.,Zollinger, Heinrich
, p. 122 - 132 (2007/10/02)
The rearrangements of 4'-methoxy-N-methyl- and N-methyl-4'-nitro-diazoaminobenzene have been studied in 20percent acetonitrile/aqueous buffers.The reactions are specifically acid catalyzed and involve pre-equilibrium formation of amine and diazonium salt
