A new transition-metal-free reductive deoxygenative olefination of phosphorus ylides with CO2, an abundant and sustainable C1 chemical feedstock, is described. This catalytic CO2 fixation afforded β-unsubstituted acrylates and vinyl ketones in good yields with broad scope and good functional group tolerance under mild reaction conditions. Cost-effective and easily handled polymethylhydrosiloxane was
描述了一种新的无过渡金属的磷酰磷与CO 2的无过渡金属还原性脱氧烯化反应,CO 2是一种丰富且可持续的C1化学原料。通过该催化CO 2固定,可在温和的反应条件下以良好的收率,宽范围和良好的官能团耐受性获得β-未取代的丙烯酸酯和乙烯基酮。具有成本效益且易于处理的聚甲基氢硅氧烷被用作还原剂。事实证明,双(甲硅烷基)乙缩醛是该CO 2还原功能化的关键中间体。
