A general Pd-catalyzed synthesis of amides by oxidative aminocarbonylation of arylsilanes under mild conditions was accomplished for the first time. The reaction is promoted by a commercially available copper(II) fluoride, which acts as a dual silane activator and mild oxidant, enabling highly efficient aminocarbonylation of versatile arylsilanes at atmospheric CO pressure. The reaction is tolerant
首次完成了在温和条件下通过芳基硅烷的氧化氨基羰基化反应进行的一般Pd催化的酰胺合成。该反应由市售的氟化铜(II)促进,该氟化铜充当双硅烷活化剂和温和的氧化剂,可在大气CO压力下对多种芳基硅烷进行高效氨基羰基化。该反应可耐受各种芳基硅烷,并且各种敏感的卤化物官能团以及广泛的胺均与使用廉价CO的氧化过程兼容。一个重要方面涉及催化剂体系效率的提高。该反应代表着有机硅烷强大的Pd催化的氧化转化。
