WebThe carboxylate-assisted cobalt catalysis was characterized by high functional group tolerance and ample substrate scope. Mechanistic studies provided evidence for a facile C–H activation. The C–H amidation was achieved in a thermal fashion as well as by means of mechanochemistry, providing access to synthetically meaningful aminoketones. WebJan 15, 2024 · It has a thiocarbonyl functional group with the sulfur bearing a partial charge of −0.305, which is slightly lower than that for Tu, a negative electrostatic potential around the sulfur, and a π*-antibonding orbital as its LUMO. Accordingly, TA also satisfies all three criteria and has demonstrated catalytic effect.
