  Esterification in dry Media Using Ferric Perchlorate Adsorbed on Silica Gel

  摘要：

  Adsorption of Fe(ClO4)(3)(H2O)(6) onto chromatographic grade silica gel in the presence of alcohol (to be used for esterification) produces a supported reagent, Fe(ClO4)(3)(ROH)(6)/SiO2. This reagent, has been found effective for the rapid and high yield of esters, on grinding in the presence of carboxylic acids using pestle and mortar in the solid state.
