Since its development in the early 1970s, the palladiumcatalyzed Heck reaction has become a powerful tool for the alkenylation of aryl and alkenyl electrophiles in chemical synthesis [Eq.(1)].[1] Thus far, alkyl halides have had limited application in Heck-type reactions, with only isolated examples available for primary alkyl halides [1b, 2] and both secondary and tertiary alkyl halides remaining almost unstudied.[3] This may be because of facile β- ...
