Abstract

Temperature dependent ¹H NMR study has been performed on the substrate complex derived from zinc(II) perchlorate, (R,R)-4,6-dibenzofurandiyl-2,2'- bis(4-phenyloxazoline), and 3-acetyl-2-oxazolidinone in deuteriodichloromethane. At room temperature, two isomers of octahedral substrate complexes are rapidly exchanging through a trigonal bipyramid intermediate. Liberation of the DBFOX/Ph ligand from the substrate complex can not be observed in a wide range of temperature, showing high stability of the DBFOX/ph · Zn(CIO₄)₂ complex.
