There is growing interest in compounds containing functionalized E=E multiple bonds (E=Si, Ge, Sn, Pb) because of their potential to exhibit novel physical and chemical properties. However, compounds containing multiple functionalizations are rare, with scarcity increasing with increasing degree of substitution. The first ditetrelene R2E=ER2 in which the E=E bond is substituted by four heteroatoms
含有官能化的E = E多个键(E = Si,Ge,Sn,Pb)的化合物由于其具有表现出新的物理和化学性质的潜力,因此引起了越来越多的关注。但是,含有多种官能团的化合物很少见,其稀缺度随取代度的增加而增加。描述了其中E = E键被四个杂原子(除了Si)取代的第一二etrelrelene R 2 E = ER 2。容易从SiBr 4和[[Mes)2之间的反应中分离出四磷二甲硅烷基(Mes)2 P} 2 Si = Si P(Mes)2 } 2(7)。P] Li,后者用作牺牲还原剂。介绍了7的结构,同时使用DFT计算探查了7的键合和稳定性。
