Paragraph 0067-0070, (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.

Novel C-S cross-dehydrogenative coupling (CDC) approaches for the selective synthesis of thioesters and thioethers have been developed via sp3 C-H activation of methylarenes and subsequent functionalization. The reaction of methylarenes with thiols resulted in thioesters in the presence of a FeBr2/TBHP system, while treatment of methylarenes with thiols in the Pd(OAc)2/O2/TBHP system led to the formation of thioethers. Both the green protocols demonstrate good functional group tolerance and satisfactory yields. This journal is
