摘要：

Titanium complexes bearing a pyridinediamide ligand [2,6-(RNCH(2))(2)NC5H3](2-) (R = 2,6-diisopropylphenyl (BDPP); R = 2,6-dimethylphenyl (BDMP)) have been synthesized. The dichloride complexes [2,6-(RNCH(2))(2)NC5H3]TiCl2 are prepared in high yield from {2,6-[(Me(3)Si)RNCH(2)]2NC5H3} and TiCl4 via the elimination of 2 equiv of CiSiMe(3). Mono(alkyl) and bis(alkyl) complexes are prepared from [2,6-(RNCH(2))(2)NC5H3]TiCl2 and various Grignard reagents. A single-crystal X-ray diffraction study of (BDMP)TiBr(CH(2)CMe(2)Ph). C6H6 (8b . C6H6) revealed a distorted square pyramid structure with the neophenyl group occupying the axial position.
