Recently Zr-catalyzed CC bond formation reactions via Zralkene complexes have been reported. 2 For allylic compounds, catalytic CC bond formation using the Cp2ZrC12lEtMgBr system proceeded at the,% carbon of allylic compounds. 2a-cd To the best of our knowledge, however, the Zr-catalyzed allylation reaction (eq 1) has not been successful using this system. 3
