Abstract
In the presence of a catalytic amount of Pd (0), active methylene compounds were allylated by allyl imidates under neutral conditions. In allylation with 3, 3-disubstituted allyl imidates, eg, geranyl and neryl imidate the effect of solvent and ligand to the E/Z ratio are investigated. The reaction in dimethyl sulfoxide by addition of diphosphine, eg, 1, 2-bis (diphenylphosphino) ethane, or large excess of triphenylphosphine as additive ligand ...
