Abstract

R. P. Chamoli, P. C. Gupta* and C. L. Taploo*

2- Aroy)benzoic acids exist in Keto-acid (chain) and lactol (ring) tautomeric forms. The effect of solvent* and substituents on the tautomeric equibrium of these acids has been described. Besides the formation of pseudo chlorides and pteudo esters etc., the lactol form undergoes condensation with phenols to form unsymmetrically substituted phthalides.

Observations; 2-Aroylbenzoic
