✦ Synopsis

Swnmary: T-butyl 2,2,2-trichloroaceiimi&e (l), reaa?ly prepared by addition of t-butawl to trichloroacetonitrile, is an efficient reagent for the preparation of t-butyl ethers and esters in the presence of a catalytic amount of boron trifhon& etherate.

Traditional methods for the preparation of t-butyl ethers and esters rely upon the use of isobutene in the presence of strong acid (e.g. concentrated sulphuric acid' 3 2 or phosphoric acid in the presence of boron trifluoride etherate') for generation of the t-butyl cation. More recent methods for the preparation of t-butyl esters involve conversion of a carboxylic acid to a mixed anhydride, followed by addition of t-butanol.4 An alternative approach, due to
