Unusual Solvent Effect on the Cycloadditions of Aromatic Nitrile N-Oxide with Alkyl Substituted p-Benzoquinones in Ethanol-Water Systems

Article abstract of DOI:10.1246/bcsj.64.3079

The second-order rate constants of 1,3-dipolar cycloaddition reactions of 2,6-dichlorobenzonitrile N-oxide (1) with 2,5-dimethyl-p-benzoquinone (2a) or 2,6-diisopropyl-p-benzoquinone in various solvents at 20 deg C were determined by spectrophotometric me
