Direct carboxylation of acetylene with CO2 was carried out in the presence of 1,5,7-triazabicyclo[4.4.0]dec-1-ene (TBD); subsequent reduction of dicarboxylated acetylene produces commercially valuable succinate salts. This metal-free carboxylation has potential economic and environmental impact by utilizing non-petroleum feedstocks (acetylene) and CO2 and by producing valuable chemical feed stocks

Binuclear molybdenum alkoxide as the versatile catalyst for the conversion of carbon dioxide
The triply bonded dimolybdenum compound, Mo2(OtBu)6 (1), was investigated as a homogeneous catalyst for the conversion of CO2. The compound 1 acted as a rare example of a versatile catalyst with an impressive ability to transform CO2 into various valuable products, including propiolic acids, cyclic carbonates, and benzo[d]thiazole- and benzo[d]oxazolecarboxylic acids, in high yields with short reaction
