Abstract:
We declare after 40 years of a convention on the structure of allylic intermediates on ZnO surface that the surface allylzinc species exists in the form of σ,π-allyl rather than exclusively
as the π-allyl complex as implied by Dent and Kokes (J. Am. Chem. Soc., 1970, 92, 1092). Olefin interaction with ZnO has been monitored by 13C cross-polarization magic angle spinning NMR. NMR shows that dissociative adsorption of propene and n-butene on ZnO surface results in the formation of carbanionic allylzinc complexes with a η1,η2-like fashion of allyl bonding to the zinc cations (σ,π-allyls). Formation of π-allylzinc complex (η3-like fashion of bonding to Zn) only as the minor species was also observed in case of propene.
