Dichloro-bis(aminophosphine) complexes of palladium with the general formula [(P(NC5H10)3−n(C6H11)n})2Pd(Cl)2] (where n = 0–2) are easily accessible, cheap and air stable, highly active and universally applicable C–C cross-coupling catalysts, which exhibit an excellent functional group tolerance. The ligand composition of amine-substituted phosphines (controlled by the number of P–N bonds) was found
通式为[[P (NC 5 H 10)3- n(C 6 H 11)n })2 Pd(Cl)2 ]的钯的二氯双(氨基膦)配合物(其中n = 0–2)易于获得,价格低廉且空气稳定,高度活跃且通用的C–C交叉耦合催化剂,具有出色的官能团耐受性。这配体 组成 胺取代的 膦类 (受P–N键的数量控制)被发现可以有效地确定其在Heck反应中的催化活性,为此 纳米粒子被证明是它们的催化活性形式。二氯bis [bis [1,1',1''-(膦三基)三哌啶]]钯(1)质子)在[(P (NC 5 H 10)3- n(C 6 H 11)n })2 Pd(Cl)2 ](其中n = 0–3)系列中,是一个高活性的Heck催化剂 在100°C的温度下,因此是有效且通用的Heck的罕见例子 催化剂可以在温和的反应条件下(100°C或更低)有效运行,对于二氯-双(1,1'-(环己基膦基二基)二哌啶)钯(2,n = 1
