Abstract
| - The condensation of C,O,O-tris(trimethylsilyl)ketene acetal 1 with aldehydes 2 in the presence ofcatalytic amounts of mercuric iodide at room temperature affords syn and antiβ-trimethylsiloxyα-trimethylsilyl alkanoic acid silyl esters 3 in good yields. These new compounds gave, under acidicor basic conditions, E and (or) Z enoic acids 4. The paths for the formation of these alkenoic acidsare discussed.
