Wang, Wan-Hui; Jia, Lihong; Feng, Xiujuan; Fang, Dingqiao; Guo, Hongyu; Bao, Ming published the artcile< Efficient Carboxylation of Terminal Alkynes with Carbon Dioxide Catalyzed by Ligand-Free Copper Catalyst under Ambient Conditions>, Product Details of C9H5ClO2, the main research area is propiolic acid preparation; terminal alkyne carbon dioxide carboxylation copper catalyst.
The combined use of simple copper salts and quaternary ammonium salts in a low-boiling-point solvent is presented as a new strategy for terminal alkynes RCCH (R = Ph, 2-thienyl, t-Bu, etc.) carboxylation with CO2 under ambient conditions. The ligand-free copper-catalyzed carboxylation was achieved with CuCl, nBu4NOAc, and K2CO3 in MeCN to produce various propiolic acids RCCC(O)OH in high to excellent yields.
Asian Journal of Organic Chemistry published new progress about Alkynes, α- Role: RCT (Reactant), RACT (Reactant or Reagent). 3240-10-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C9H5ClO2, Product Details of C9H5ClO2.
