Metalated diphosphanylsiloxanes with polycyclic and polymeric structures
摘要:
The reactions of the diphosphanylsiloxane O(SiiPr(2)PH(2))(2) (1) with MiPr(3) (M = Ga, In) produced the polycyclic compounds [O{SiiPr(2)(PH)MiPr(2)} {SiiPr(2)(P)MiPr}](2) (2, 3). Compounds 2 and 3 are composed of three M2P2 rings forming a ladder structure and two OSi2P2M rings. By reactions of 1 with n-BuLi the polymeric compound [O(SiiPr(2)PHLi)(2)(THF)(TMEDA)] center dot THF (4) was obtained. (c) 2006 Elsevier B.V. All rights reserved.
