Recently, the efficient chemical fixation of carbon dioxide (CO₂) into high value chemicals without using noble metal catalysts has become extremely appealing from the viewpoint of sustainable chemistry. In this work, a one-pot three component reaction of propargylic alcohols, anines and CO₂ that can proceed in an atom economy and environmentally benign manner by combination of CuI and tetrabutylphosphonium imidazol ([P][Im]) as a catalyst was described. Catalysis studies indicate that this catalytic system is an effective catalyst for the conversion of CO₂ into oxazolidinones at room temperature and ambient pressure without any solvent. The results provide a useful way to design novel noble metal-free catalyst systems for the transformation of CO₂ into other valuable compounds.
最近，从可持续化学的角度来看，高效地将二氧化碳（CO₂）化学固定为高价值化学品而不使用贵金属催化剂变得极具吸引力。在这项工作中，描述了炔丙醇、苯胺和 CO₂的一锅三组分反应，该反应可以通过 CuI 和四丁基膦咪唑([P][Im])的组合以原子经济性和环境友好的方式进行。催化研究表明，该催化体系是在室温常压下将 CO₂转化为恶唑烷酮的有效催化剂，无需任何溶剂。该结果为设计新型无贵金属催化剂体系将 CO₂转化为其他有价值的化合物提供了有用的方法。
