FACILE ROUTE TO 1-PHOSPHORYL- AND 1-SULFONYL-1,3-DIENES VIA PALLADIUM-CATALYZED ELIMINATION OF ALLYLIC ACETATES
The palladium(II)-catalyzed chloroacetoxylation of 1,3-dienes is employed to prepare 1-chloro-4-acetoxy-2-alkenes which are then transformed into 1-phosphoryl- or 1-sulfonyl-4-acetoxy-2-alkenes respectively.Elimination of acetate is promoted by palladium(
