The catalytic enantioselective addition of different organozinc reagents, such as diethylzinc, or in situ generated phenylzinc derivatives to simple aryl methyl ketones was accomplished using titanium tetraisopropoxide and a polymeric ligand grafted with trans-1-phenylsulfonylamino-2-isoborneolsulfonylamidocyclohexane, to give the corresponding tertiary alcohols with enantioselectivities of up to >99%

Long-range NMRisotopeshifts due to γ-deuteration in carbocations are upfield, in contrast to β-deuteration effects. Such behavior is analogous to kinetic and equilibrium isotope effects in carbocation-forming reactions.
