Abstract
The addition of bis(pinacolato)diboron [(Me4C2O2)B-B(O2C2Me4)] to alpha,bet a-unsaturated ketones, esters, nitriles, or terminal alkynes and the coupli ng with allyl chlorides were carried out in DMF at room temperature in the presence of CuCl and AcOK. The transmetalation from boron to copper generat ing a B-Cu species was proposed as the key step of the reactions.
