摘要
(Chemical Equation Presented) EPR and ENDOR spectroscopies combined with DFT calculations have revealed the selective binding of a cis over a trans epoxide to a chiral vanadyl salen complex (see picture). Complementary DFT calculations identified a weak electrostatic interaction supplemented by multiple hydrogen-bonding contacts as the origins of this selectivity. These observations were experimentally confirmed in frozen solution by orientation selective ENDOR measurements. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
