Abstract

The one-pot reaction of L¹SiCl (L¹=PhC(NtBu)₂) with MesPX₂/IsPX₂ (X=Cl, Br; Is=2,4,6-iPr₃C₆H₂, Mes=2,4,6-Me₃C₆H₂) in the presence of KC₈ yielded two phosphasilene compounds L¹Si(Cl)=PIs (1) and L¹Si(Cl)=PMes (2) with interesting Cl−Si=P characteristics. The introduction of Cl−Si=P moiety improved the reactivity of phosphasilene. Furthermore, phosphasilenes 1 and 2 with LSi as well as Si=P building units are sensitive to moisture with distinct differences. The hydrolysis of 2 resulted in two products [L¹(PHMes)Si]₂(μ-O)₂ (3) and L¹Cl (4), respectively, due to the amount of water, while the hydrolysis of 1 afforded L¹Cl (4). In addition to the silylene L¹SiCl, different types of aluminum compounds were studied to react with IsPX₂/MesPX₂ in the presence of KC₈ in THF at low temperature. However, we failed to isolate the desired compounds due to the formation of numerous by-products.
