An isolable bis-silylene oxide ("disilylenoxane") and its metal coordination.
The first isolable oxygen-bridged bis-silylene 1 has been synthesized by facile dehydrochloration of the corresponding disiloxane [LSiH(Cl)-O-SiH(Cl)L] precursor [L = PhC(NtBu)(2)] with LiN(SiMe(3))(2). Compound 1 contains three-coordinate, pyramidal Si(II) atoms in a bent disiloxane-like moiety and reacts readily with [Ni(COD)(2)] to afford the unique bis-silylene oxide nickel complex 3.
