I zinc we're alone now: The title reactions were achieved in an undivided cell fitted with a pair of zinc electrodes in aqueoussolution. A preliminary study on the relationship of reaction activity and surface morphology showed that the deposited zinc powders with nanoscale architectures had very high activity.

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

Abstract Imines can be readily allylated with samarium/allylbromide system to afford homoallylamines in satisfactory yields in THF under mild conditions.
A copper-catalyzed ring-opening hydroamination of methylenecyclopropanes with polymethylhydrosiloxane and O-benzoylhydroxylamines has been developed. The cyclopropane C–C bond cleavage occurs selectively at the more congested proximal position, and the corresponding homoallylamines are obtained in good to excellent yields. The umpolung electrophilic amination strategy with the hydroxylamine derivatives
