Barbier-type Carbonyl-allylation with Allyl Compounds and SnCl2 in the Presence of PdCl2[PPh2(m-C6H4SO3Na)]2 under Two-phase Conditions
The hydrophilic palladium complex efficiently catalyzes the allylation of carbonyl compounds with allyl chlorides or allyl alcohols and SnCl2 under aqueous-organic biphase conditions, which allow us easily to separate the product and to recover the organic solvent from the reaction mixture.
