The Lewis acid-promoted reaction of 3,3-disul3stituted allyltins toward aldehydes was found to be stefeospecific; the (E)-reagent gave syn-products and the (Z)-one gave anti-products. This is in contrast to that of 3-mono-su~tituted congeners which are known to react syn-stereoselectively regardless
