Herein, we report the hydrogenation of carbon dioxide to sodium formate catalyzed by low-valent molybdenum phosphine complexes. The 1,3-bis(diphenylphosphino)propane (DPPP)-based Mo complex was found to be an efficient catalyst in the presence of NaOH affording formate with a TON of 975 at 130 °C in THF/HO after 24 h utilizing 40 bar (CO : H = 10 : 30) pressure. The complex was also active in the hydrogenation of sodium bicarbonate and inorganic carbonates to the corresponding formates. Mechanistic investigation revealed that the reaction proceeded an intermediate formato complex.
在此，我们报道了低价钼膦配合物催化二氧化碳加氢生成甲酸钠的反应。发现基于1,3-双（二苯基膦基）丙烷（DPPP）的钼配合物在NaOH存在下是一种高效催化剂，在130℃的THF/H₂O中，使用40 bar（CO∶H₂ = 10∶30）压力，24小时后TON为975时可生成甲酸盐。该配合物在碳酸氢钠和无机碳酸盐加氢生成相应甲酸盐的反应中也具有活性。机理研究表明，该反应通过中间体甲酰基配合物进行。
