Trimethylsilyl esters. Trimcthylsilyl esters are obtained in 65-90% yield by reaction ol carboxylic acids with hexamethyldisiloxane in refluxing toluene containing a catalytic amount of sulfuric acid. The actual catalyst is probably his(trimcthylsilyl) sulfate, [(CH3)3Si]2SO. Pyridinium trifluoromethanesulfonate also can serve as catalyst. 

Polymer-bound reagents for silylation have been reported. Murata and Noyori treated Nation, a perfluorinated resin-sulfonic acid, with trimethylsilyl chloride to afford a polymer-bound trimethylsilyl ester that functions as a polymer-bound equivalent of trimethylsilyl trifluoromethanesulfonate, converting alcohols, eth-anethiol and diethylamine into the corresponding silylated compounds in high yields (Scheme 6.16) [70]. Acetic acid could also be silylated, albeit with moderate conversion. The corresponding polystyrene-bound reagent is commercially available.
