Upon treatment of allyl thioethers with P 4 -t-Bu, allyl thioether anions were generated and rapidly reacted with aromatic aldehydes, leading to 1,3-dienyl sulfides in good yields with high regioselectivity. This finding provides an alternative preparation of allyl thioether anions in a regioselective manner. In addition, chemoselective transformation of 1,3-dienyl sulfides to provide the corresponding 1,3-dienyl sulfoxides or 1,3-dienyl sulfones was also demonstrated.Chemical EngineeringChemistryArticleSCOPUS10.1055/a-2259-53952-s2.0-851849108831437210X
