The phosphazene-catalyzed regioselective condensation of allyl thioethers with aldehydes is investigated. Upon treatment of allyl thioethers with P4-t-Bu, allyl thioether anions are generated and rapidly react with aromatic aldehydes, leading to 1,3-dienyl sulfides in good yields with high regioselectivity. This finding provides an alternative approach for the preparation of allyl thioether anions
