The rate of the thermal conversion of 1′,3′,3′-trimethylspiro[2<I>H</I>-1-benzopyran-2,2′-indoline]-8-carboxylic acid (8-COOH-SP) from its spiro form to its merocyanine form has been measured in several solvents at high pressures. Small solvent- and pressure-dependencies of the rate were observed. These results suggest that the electronic structure of the transition state of this reaction is nonpolar and that it is similar to that previously observed for the thermal conversion of so-called 6-nitrospiropyran from its merocyanine form to its spiro form.
