mild amine basic conditions is described. A cooperative catalysis of CpRu complex, DBU, and NaPF6 enables chemoselective and catalytic generation of nucleophiles from barely acidic acetonitrile, which is integrated into the addition to aldehydes, imines, and activated ketones. Mechanistic investigations revealed that the three catalyst components work together to achieve high catalytic efficiency.
描述了在温和的胺碱性条件下直接添加乙腈的有效催化系统的开发。CpRu络合物,DBU和NaPF 6的协同催化能够从勉强酸性的乙腈进行化学选择和催化生成亲核试剂,并将其整合到醛,亚胺和活化的酮中。机理研究表明,三种催化剂组分共同作用以实现高催化效率。
