- Abstract
- The specific rates of solvolysis of t-butyl fluoroformate (1) have been measured at 40 0 degrees C in 21 pure and binary solvents These give a satisfactory correlation over the full range of solvents when the extended Grunwald-Winstein equation, with incorporation of the solvent nucleophilicity and the solvent ionizing power, is applied The actual values are very similar to those obtained in earlier studies of the solvolyses of isopropyl chloroformate and ethyl chlorothioformate in the more ionizing and least nucleophilic solvents, which are believed to proceed by an ionization pathway The small negative values for the entropies of activation are consistent with the ionization nature of the proposed rate-determining step These observations are also compared with those previously reported for the corresponding primary and secondary alkyl haloformate esters
