N-chelate half-sandwich iridium complexes have been synthesized through a facile route in good yields. The dehydrogenation of a series of aromatic and aliphatic primary alcohols to corresponding carboxylic acids has been accomplished catalyzed by the prepared air stable iridium complexes under mild reaction conditions. Carboxylic acids were obtained in high yields under open flask condition with broad substrates
通过简便的路线,以良好的产率合成了一系列基于酰腙的N,N-螯合半夹心铱配合物。所制备的空气稳定铱配合物在温和的反应条件下催化一系列芳香族和脂肪族伯醇脱氢生成相应的羧酸。在敞口烧瓶条件下以高产率获得了羧酸,具有广泛的底物和对敏感官能团的良好耐受性。这种半夹心铱催化剂体系表现出较高的催化活性和稳定性,在催化剂负载量低至0.05 mol%的情况下即可实现316.7 h –1的高TOF。此外,这种可持续催化剂可以重复使用至少五次而不会明显失去活性,凸显了其在工业中的潜在应用。通过单晶X射线分析证实了铱配合物1的分子结构。
