CO2-assisted various symmetric and non-symmetric α-diketones have been synthesized directly from the corresponding aldehydes using transition metal-free catalysts. This method can even be applied to synthesize pharmaceuticals directly from aldehydes. The crucial role of CO2 has been investigated in detail and the mechanism is proposed on the basis of experiments and DFT calculations.
reductive coupling reaction was established for the synthesis of diaryl 1,2-dicarbonyl compounds from arylmethyl ketones in good yields. The mechanisticstudy showed the reaction undergoes C(CO)–C(sp3) bond cleavage, with the reductive coupling reaction occurring through an electron transfer process. Notably, the reaction not only is simple to operate but also has mild reaction conditions and a wide
