Adsorption of Fe(ClO4)(3)(H2O)(6) onto chromatographic grade silica ge
l 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.
