摘要: MesB(C6F5)2 (1) has been prepared from MesMgBr and FB(C6F5)2·OEt2, while Mes2B(C6F5) (2) is readily available CuC6F5 Mes2BBr. The reduction potential E° of 1 vs Cp2Fe0/+ in THF −1.72 V, that 2 −2.10 Mes3B (3) −2.73 V. 11B 1H NMR show neither nor binds significantly. These results have used to estimate the B(C6F5)3 as −1.17 V or −0.64 SCE.
