Allyliczinc reagents have been prepared from sterically hindered homoallylic alcohols 10 and 13, using a novel fragmentation reaction of the corresponding zinc alkoxide, without any homocoupling products. These allyliczinc reagents react with a range of electrophiles in good to excellent yields. Substitutedallyliczinc reagents have also been prepared in this manner. alpha-Substituted homoallylic
