Correlation analysis of reactivity in the oxidation of substituted benzyl alcohols by benzimidazolium dichromate - A kinetic and mechanistic aspects

The oxidation of a number of para- and meta-substituted benzyl alcohols by benzimidazolium dichromate (BIDC), in dimethyl sulphoxide, leads to the formation of the corresponding benzaldehydes. The reaction is first order with respect to each BIDC and alcohol. The reaction is catalyzed by hydrogen ions and the dependence has the form kobs = a + b[H+]. The oxidation of [1,1-2H2]benzyl alcohol exhibited the presence of a substantial kinetic isotope effect. The rates of the oxidation of meta-substituted benzyl alcohols correlated best with Taft's σ1 and σR0 constants. The para-substituted compounds exhibited excellent correlation with σ1 and σRBA values. The polar reaction constants are negative. The rate of oxidation of benzyl alcohol was determined in nineteen organic solvents. An analysis of the solvent effect by multiparametric equations indicated the greater importance of the cation-solvating power of the solvents. Suitable mechanisms have been discussed.

EXCHANGE REACTIONS OF SUBSTITUTED BENZALDEHYDE HYDRAZONES

Hydrazones IV, derived from substituted benzaldehydes and N-aminophthalimide, experience an exchange reaction with one equivalent of 2,4-dinitrophenylhydrazine under conditions free of added mineral acid to cleanly and irreversibly produce the related 2,4-dinitrophenylhydrazones V in good yields.Although literature melting points for compounds V may vary from one reference to another, the infrared spectra (ν (mull), cm-1; IV: 1770, 1710; V: 3280, 1615, 1580, 1510) of starting materials and products in the exchange process are strikingly different and permit ready characterization.

A New Ring Opening Reaction of N-Aminophthalimide Hydrazones

Araldehyde hydrazones III of N-aminophthalimide underwent rapid ring opening reactions initiated by the addition of excess base to their refluxing methanolic solutions.The products were conveniently isolated through liquid-liquid extraction as the stable
