A catalyst of a new type, cyclobutadiene complex [(C4Et4)Rh(p-xylene)]PF6, was found to promote selective reductive amination in the presence of carbon monoxide under mild conditions (1–3 bar, 90 °C). The reaction demonstrated perfect compatibility with a wide range of functional groups prone to reduction by conventional reducing agents. The developed system represents the first systematic investigation
发现一种新型的环丁二烯络合物[(C 4 Et 4)Rh(对二甲苯)] PF 6的催化剂可在温和条件下(1-3 bar,90° C)。该反应证明与易于被常规还原剂还原的各种官能团具有完美的相容性。开发的系统代表了环丁二烯金属配合物作为催化剂的首次系统研究。
