| Abstract: | The dialk-2-enylzinc compounds I–IV add to ethylene, oct-1-ene and 3,3-dimethylcyclopropene to give the corresponding di-alk-4-enylzinc compounds VI–IX (88–98% yield), XV and XVI (90–94% yield), XVII (7%) and XXIIIa–XXVIa (91–98% yield). Additions to XIII are regioselective with Zn → C(1) while stereoselective cis-addition to XXII is observed. |
