Abstract
The novel precursor [ButNHP(μ-NBut)2PNH2] (1) provides easy access to polycyclic main group systems; reaction with Sb(NMe2)3 gives the tricyclic species {[ButNHP(μ-NBut)2- P}2{Me2NSb(μ-N)}2] (2), whereas reaction with an excess of BunLi results in elimination of LiNH2 and the formation of the co-complex [{ButNP(μ-NBut)2P}2 N]Li3 (BunLi)2, (3), containing the unprecedented [{ButNP(μ-NBut)2P}2 N]3− trianion.
