aldehydes in the presence of catalytic amounts of fluoride ion to afford adducts in moderate to excellent yields with perfect retention of its geometry stereospecifically. These adducts were also subjected to the conditions of [3,3] sigmatropic rearrangements to give esters or aldehydes in moderate yields.
