资源简介：
Treatment of iPr2NP(C9H7)(C2B10H11) with excess 30% hydrogen peroxide in toluene gave the corresponding pentavalent phosphorus-bridged indenyl−carboranyl compound iPr2NP(O)(C9H7)(C2B10H11) (2). The equimolar reaction of 2 with M(NR2)4 in toluene at room temperature afforded unexpected group 4 metal amides incorporating an indenylide unit, [σ:σ-iPr2NP(O)(C9H6)(C2B10H10)]M(NR2)2(L) (R = Me, L = HNMe2, M = Ti (3), Zr (4), Hf (5); R = Et, L = THF, M = Hf (6)). The formation of these new types of group 4 metal complexes was ascribed to the high oxophilicity of the M4+ ions. These new complexes were fully characterized by various spectroscopic techniques, elemental analyses, and single-crystal X-ray diffraction studies (except for 5).
