Cationic species derived from the η1-amidosilyl-η5-cyclopentadienyl dimethyl titanium complex. Crystal structure of [Ti{η5-C5H4SiMe2[η1-N(2,6-Me2C6H3)]}{CH2B(C6F5)2}(C6F5)]
Reactions of the η5-cyclopentadienyl-η1-amido dimethyl titanium derivative [Ti{η5-C5H4SiMe2[η1-N(C6H3Me2)]}Me2] (1) with tris(pentafluorophenyl)borane B(C6F5)3 in hexane at room temperature yield a thermally stable bright yellow microcrystaline solid identified by elemental analysis as [Ti{η5-C5H4Si...

| Sumario: | Reactions of the η5-cyclopentadienyl-η1-amido dimethyl titanium derivative [Ti{η5-C5H4SiMe2[η1-N(C6H3Me2)]}Me2] (1) with tris(pentafluorophenyl)borane B(C6F5)3 in hexane at room temperature yield a thermally stable bright yellow microcrystaline solid identified by elemental analysis as [Ti{η5-C5H4SiMe2[η1-N(C6H3Me2)]}Me{MeB(C6F5)3}] (2). A solution of 1 in CD2Cl2 at −78°C affords the ion-pair complex 2, while in C6D6 it is slowly converted into the new neutral complex [Ti{η5-C5H4SiMe2[η1-N(C6H3Me2)]}{CH2B(C6F5)2}(C6F5)] (3). Complex 3 is the unique product obtained after stirring compound 2 or a mixture of complex 1 and B(C6F5)3 in toluene or benzene for 12 h at room temperature. The molecular structure of complex 3 has been determined by diffraction methods. |
