Zhang, Qiao; Yuan, Hao-Yu; Lin, Xiao-Tao; Fukaya, Norihisa; Fujitani, Tadahiro; Sato, Kazuhiko; Choi, Jun-Chul published an article in 2020, the title of the article was Calcium carbide as a dehydrating agent for the synthesis of carbamates, glycerol carbonate, and cyclic carbonates from carbon dioxide.Synthetic Route of 102-07-8 And the article contains the following content:
Carbon dioxide (CO2) is a nontoxic and inexpensive C1 building block, which can be used for the synthesis of valuable chems. such as aromatic carbamates from anilines and methanol (MeOH), glycerol carbonate from glycerol, and cyclic carbonates from diols. However, these reactions generate water as the byproduct and suffer from thermodn. limits, which lead to low yields. Calcium carbide (CaC2) is a renewable chem., which can be recycled from calcium that is abundant in the Earth’s crust. Furthermore, CaC2 rapidly reacts with water. The authors used CaC2 as a dehydrating agent for the direct synthesis of carbamates (including polyurethane precursors) from amines, CO2, and MeOH. All reagents were com. available. In addition, CaC2 was employed for the synthesis of glycerol carbonate from glycerol and CO2 with a zinc catalyst and N-donor ligand. A similar protocol was applied to synthesize cyclic carbonates from diols and CO2. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Synthetic Route of 102-07-8
