zinc bromides and regioconvergent Negishi coupling with aryl or alkenyl triflates. The use of a suitable phosphine ligand favoring Pd migration enabled the selective formation of the linear cross‐coupling product. Subsequently, mixtures of secondary alkyl bromides were prepared from linear alkanes by standard bromination, and regioconvergent cross‐coupling then provided access to the corresponding linear

Various aryl triflates derived from phenols were converted into aryl esters or amides in good yields by a palladium-catalyzed reaction with carbon monoxide and alcohols or amines.
