Quality Control of Tri(naphthalen-1-yl)phosphine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about C-H Bond Activation by Radical Ion Pairs Derived from R3P/Al(C6F5)3 Frustrated Lewis Pairs and N2O. Author is Menard, Gabriel; Hatnean, Jillian A.; Cowley, Hugh J.; Lough, Alan J.; Rawson, Jeremy M.; Stephan, Douglas W..
Al(C6F5)3/R3P [R = tert-Bu (tBu), mesityl (Mes), naphthyl (Nap)] frustrated Lewis pairs react with N2O to form species having the formula R3P(N2O)Al(C6F5)3, which react with addnl. alane to generate proposed frustrated radical ion pairs formulated as [R3P·][(μ-O·)(Al(C6F5)3)2] that can activate C-H bonds. For R = tBu, C-H activation of a tBu group affords [tBu2PMe(C(CH2)Me)][(μ-OH)(Al(C6F5)3)2]. In the case of R = Mes, the radical cation salt [Mes3P·][(μ-HO)(Al(C6F5)3)2] is isolated, while for R = Nap, the activation of toluene and bromobenzene gives [(Nap)3PCH2Ph][(μ-OH)(Al(C6F5)3)2] and [(Nap)3PC6H4Br][(μ-HO)(Al(C6F5)3)2], resp.
After consulting a lot of data, we found that this compound(3411-48-1)Quality Control of Tri(naphthalen-1-yl)phosphine can be used in many types of reactions. And in most cases, this compound has more advantages.
