demonstrated to heterogeneously catalyze visible light-induced reduction of phenyl, benzyl, 2-phenylethyl and 3-phenylpropyl azides in acetonitrile to produce the corresponding amines in good to high yields. For the last two kinds of azides that bear a CO2Me group at the para-position of the benzene ring, cascade reactions take place to generate the corresponding lactams in high yields. Compared with
摘要已证明,由[Ru(bpy)3] 2+衍生的六臂分子和葫芦[8] uril组装而成的以Ru(bpy)3] 2+为核心的超分子有机骨架SMOF-1,可异质催化可见光,诱导还原乙腈中的苯基,苄基,2-苯基乙基和3-苯基丙基叠氮化物,从而以高至高收率生产相应的胺。对于在苯环的对位带有CO2Me基团的最后两种叠氮化物,发生级联反应以高收率生成相应的内酰胺。与均相对照[Ru(bpy)3] Cl2相比,SMOF-1表现出显着提高的光催化活性,这是由于[Ru(bpy)3] 2+单元形成了形成立方笼的叠合分子和相关分子的协同作用的结果。中间体。而且,
