An efficient inexpensive cobalt(iii)-catalyzed intermolecular amidation of N,N-dialkyl thiobenzamides with 1,4,2-dioxazol-5-ones via C-H bond activation is described. The reaction proceeds with high functional group tolerance under external oxidant free conditions, providing a straightforward approach for the direct modification of thioamide derivatives, which are prevalent organic motifs found in vital biological and pharmaceutical molecules.

Paragraph 0056-0058, (2021/03/31)
The invention discloses a method for preparing an aryl thioamide compound. The method comprises the following steps: under the protection of inert gas, performing stirring to react for 6-12 hours at the reaction temperature of room temperature to 60 DEG C by taking aryl methanol as a substrate, sublimed sulfur as a sulfur source, an alkali metal complex formed by combining alkali metal salt and ligand as a catalyst, alkali as an accelerant, formamide as a solvent and an amine source; and carrying out post-treatment on the reaction product to obtain the aryl thioamide compound. According to theinvention, cheap and easily available aryl methanol is used as a substrate for three-component reaction to prepare the corresponding thioamide compound; the method for preparing the aryl thioamide compound has the technical advantages of simple technological process, high yield, less pollution, safety, environmental protection, greenness, mildness and the like.

We report ruthenium(II)-catalyzed ortho-C-H arylation of N,N-dialkylthiobenzamides with boronic acids. The method employs [RuCl2(p-cym)]2 in the presence of Cu(OTf)2 and Ag2O oxidant. The reaction represents the first example of Ru-catalyzed C-H arylation directed by sulfur-containing groups and a rare example of C-H arylation directed by the versatile thiobenzamide moiety. As a further advantage, the method is performed in sustainable and eco-friendly 2-MeTHF as a solvent.
