A mild and chemoselective double allylboration of nitriles and acid anhydrides to form bis-allyl amines and esters, respectively, can be achieved through the use of potassium allyltrifluoroborate in the presence of boron trifluoride etherate at room temperature. The reaction with an operationally stable and robust potassium organotrifluoroborate reagent avoids the use of metals.
