CuCl 2与4当量的Ph 2 SiO 2 Li 2在THF中反应,生成Cu(μ-OSiPh 2 OSiPh 2 O)2 [Li(THF)2]2,产率80%。CuBr 2反应类似。这些反应的产物具有含有两个和两个环的螺环金属硅氧烷结构。
Abstract CuCl2 reacts with four equivalents of Ph2SiO2Li2 in THF to form Cu(μ-OSiPh2OSiPh2O)2 [Li(THF)2]2 in 80% yield by formal elimination of Li2O and LiCl. CuBr2 reacts analogously. The product of these reactions has a spirocyclic metallasiloxane structure containing two and two rings.
