We have presented the first palladium(II)‐thiadiazole‐ligand catalytic system, employing 1,3,4‐thiadiazole derivative as ligand to achieve the esterification of terminal olefin with excellent regio‐ and stereoselectivity. This work is significant in that it represented the first application of 1,3,4‐thiadiazole in organic synthesis. Furthermore, it was also featured by its satisfied yields, mild reaction

A palladium catalyst that converts terminal olefins to linear allylic acetates at lower catalyst loadings and faster reaction times than current systems is reported. This reaction can be conducted using benzoquinone as the oxidizing agent or catalytic amounts of copper and hydroquinone under one atmosphere of oxygen.
