Monosubstituted acyclic (E)-1,3-dienes undergo efficient hydrovinylation giving (Z)-3-alkylhexa-1,4-dienes upon treatment with catalytic amounts of bidentate phosphine-CoCl2 complexes and Me3Al in an atmosphere of ethylene. Complexes derived from (RR)-DIOP and (SS)-BDDP at -45C give very high enantioselectivities for several prototypical 1,3-dienes.
