Metallafuran complexes with a fused five‐membered phosphonium ring were synthesized from reactions between terminal ynones HC≡C(C=O)R and cis‐[Ru/Os(dppm)2Cl2] (dppm=1,1‐bis(diphenylphosphino)methane). A metal–vinylidene‐involving pathway was found to be an energetically feasible formation mechanism for these complexes. These phosphonium‐containing metallafurans, like many phosphonium‐functionalized
由末端酮HC≡C(C = O)R与顺式-[Ru / Os(dppm)2 Cl 2](dppm = 1,1-双(二苯基膦基)甲烷)。人们发现,涉及金属-亚乙烯基的途径是这些络合物在能量上可行的形成机理。像许多metal功能化的药物一样,这些含phospho的金属呋喃也具有诱导线粒体功能障碍的能力。与它们的金属前体和经典的抗癌药顺铂相比,它们还对几种人类癌细胞系表现出更强的细胞毒性。总体而言,这项工作通过Ru II和Os II中心激活炔烃,为功能性金属环的合理设计提供了结构和机理方面的见解。
