                                    Experimental details are reported for the silylation of esters by  a method based upon in situ preparation of triethylsilyl  perchlorate. The preparation of ethyl triethylsilyldiazoacetate  (5) in 99% yield from ethyl diazoacetate (3)  is detailed. A preparative procedure for the stereoselective formation  of a (Z)-O-silylketene acetal 2b from isopropyl  propanoate (1) is described.
