摘要：

The amino acid Schiff base manganese complex (Sal-Phe-Mn) was prepared with L-phenylalanine, salicylaldehyde and Mn(OAc)(2). 4H(2)O. The ligand and the complex were characterized by the infrared spectra, small area X-ray photoelectron spectroscopy,:and ICP-AES. in the presence of the manganese complex, cyclohexene was effectively oxidized by molecular oxygen without reductant. The major products of the reaction were 2-cyclohexen-1-ol (-OH), 2-cyclohexen-1-one (C=O) and 2-cyclohexen-1-hydroperoxide (-OOH), which was different with typical oxidation of cyclohexene. The influence of reaction temperature and additive for oxidation had been studied. The selectivity of 2-cyclohexen-1-hydroperoxide varied with reaction time and different additives. The mechanism of cyclohexene oxidation had also been discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
