The preparation of novel phosphinite- and phosphonite-bearing copper(I) complexes of the general formula [CuX(L)] is reported. These compounds, which remain scarce in the literature, could be prepared using readily available starting materials and were spectroscopically and structurally characterized. These complexes, together with their known phosphine and phosphite analogues, were then applied to
报道了通式[CuX(L)]的新型次膦酸酯和亚膦酸酯的含铜(I)配合物的制备。这些化合物在文献中仍然很少,可以使用容易获得的起始原料制备,并在光谱和结构上进行表征。然后将这些配合物及其已知的膦和亚磷酸酯类似物一起用于叠氮化物和炔烃的1,3-偶极环加成反应,以发现新的配合物表现出最佳的活性。完全优化反应条件导致了一个值得注意的Click催化系统,该催化系统在非常温和的反应条件下,没有任何添加剂且使用低金属负载的情况下具有活性。
