A new approach to the synthesis of cage-like metallasiloxanes
摘要:
A new approach to the synthesis of cage-like metallasiloxanes has been proposed. Copper-containing metallasiloxanes {Na-4[(RSiO2)(12)Cu-4](R'OH)(n)} (la, R = Ph, R' = n-Bu; Ib, R = Ph, R' = Me; 2, R = Vi, R' = Me) were prepared from Ph-Si(OR)(3).(R = n-BU, Me) and ViSi(OMe)(3), respectively. Compound 2 was characterized by X-ray single structure analysis. The structures of compounds la,b were deduced by their follow up reactions with Me3SiCl. (C) 1998 Elsevier Science S.A.
