摘要

In this paper we present the synthesis of several sulfurdiimido phosphanyllithium complexes that are oxidised with oxygen, sulfur or selenium at the phosphorus atom. Starting from the P III-containing [Li{tBu _2PCH _2S(NSiMe _3) _2}] _2 (1) we synthesised and structurally characterised [Li{tBu _2P(E)CH _2S(NSiMe _3) _2}] _2 (E = O: 2,E = S: 4, E = Se: 5) and [Li 2{tBu _2PCH _2S(NSiMe _3) _2} _2(tBu _2P(O)Me)](3). The oxidised and unoxidised species are discussed with respectto their coordination properties and in terms of ligand design. Acomparison to the potential polymerisation catalyst[(C _3H _7)Ni{tBu _2PCH _2S(NSiMe _3) _2}] is presented as well.
