-
Paragraph 0063-0066, (2020/12/09)
The invention discloses a method for preparing a benzoic acid-S-phenyl ester compound shown as a formula (IV) through cuprous catalysis. The preparation method comprises the following steps of: preparing a reaction product from a benzaldehyde compound shown as a formula (I), elemental sulfur shown as a formula (II) and an iodobenzene compound shown as a formula (III) by using cuprous iodide as a catalyst, tetraethylammonium bromide as an alkali and N, N-dimethylformamide as a medium, and carrying out post-treatment on the reaction product to obtain the benzoic acid-S-phenyl ester compound, wherein the formulas are described in the specification. The method is efficient in chemical agent and low in cost; and the catalytic system has wide adaptability and is suitable for large-scale production of chemical intermediates.

experimental part, p. 561 - 569 (2009/04/05)
The effect of the substituent nature on the rate and activation parameters of transesterification of a series of 4-nitrophenyl benzoates with benzenethiol in dimethylformamide in the presence of potassium carbonate was studied by the competing reaction method. In all cases, change of the Gibbs energy of activation is determined mainly by variation of the enthalpy of activation. 4-Nitrophenyl benzoates having electron-withdrawing substituents in the benzoyl fragment were found to fit an isokinetic relation with an isokinetic temperature β of 318 K. Enthalpy-entropy compensation effect was observed in the reactions with all the examined 4-nitrophenyl benzoates. The relation between the reactivity and polarizability of nucleophilic center in S-and O-nucleophiles is discussed.
