A. Levina et al., ON THE STABILITY OF THE COPPER-(S)-PROLINE CATALYST IN THE ENANTIOSELECTIVE ALLYLIC ACYLOXYLATION OF ALKENES, Journal of organometallic chemistry, 494(1-2), 1995, pp. 165-168
Visible spectroscopic studies of the enantioselective allylic benzoylo
xylation of cyclohexene by t-butyl peroxybenzoate in the presence of c
atalytic amounts of Cu{(S)-proline}(2) indicate that this chelate rema
ins largely unmodified under the experimental conditions.
