Reaction of thioamides (e.g., II) with benzynes generated by the hexadehydro-Diels-Alder (HDDA) cycloisomerization (e.g., I) produces dihydrobenzothiazines (e.g., III). It is postulated that the reaction proceeds via benzothietene (cf. IV) and o-thiolatoa

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.
Rhodium-catalyzed direct coupling of benzothioamides with alkenes and alkynes through directed C-H bond cleavage

Rhodium-catalyzed direct coupling of benzothioamides with alkenes proceeds smoothly involving ortho-CH bond cleavage. The thioamides also couple with alkynes under similar conditions accompanied by desulfurization and CN bond cleavage to produce indenone derivatives.
