Two cage copper(II)silsesquioxanes, namely, tricopper complex (PhSiO_1.5)₈(CuO)₃(TMEDA)₂*(MeCN)₃ Cu-1 and hexacopper complex (MeSiO_1,5)₁₂(CuO)₆(Py)₆*TMEDA Cu-2 were synthesized (in 30% and 16% yield, respectively) via TMEDA-assisted reactions (TMEDA = tetramethylethylenediamine). Structural features of both products were established by X-ray diffraction study. Complexes Cu-1 and Cu-2, along with some Cu(II)-silsesquioxanes reported earlier, were evaluated for the first time as precatalysts for the homogeneous Chan-Evans-Lam (CEL) O-arylation of benzoic acids (the highest yield of phenylbenzoic ester was 84%). Observed catalytic activity was superior to reference catalyst Cu(OAc)₂*H₂O. Finally, an application of coppersilsesquioxanes allowed to observe the first example of C-O CEL coupling under microwave activation characterized by (i) reduced loading of copper, (ii) low amount of added base, (iii) minimization of the time of reaction.

两种笼型铜（II）倍半硅氧烷，即三铜配合物（PhSiO _1.5）₈（CuO）₃（TMEDA）₂ *（MeCN）₃ Cu-1和六铜配合物（MeSiO _1,5）₁₂（CuO）₆（Py）通过TMEDA辅助反应（TMEDA =四甲基乙二胺）合成了_6种* TMEDA Cu-2（分别以30％和16％的收率）。两种产品的结构特征均通过X射线衍射研究确定。配合物Cu-1和Cu-2，以及较早报道的一些Cu（II）-倍半硅氧烷，首次被用作均相苯甲酸的Chan-Evans-Lam（CEL）O-芳基化的预催化剂（苯基苯甲酸酯的最高收率为84％）。观察到的催化活性优于参考催化剂的Cu（OAc）₂ * H ₂ O.最后，coppersilsesquioxanes的允许观察微波活化的特征在于（下耦合CO CEL的第一例的应用程序我）还原铜的负载，（II）碱添加量低，（iii）反应时间最短。
