The base-free thorium terminal imido [η5-1,2,4-(Me3C)3C5H2]2ThN(p-tolyl) (1) activates a variety of small molecules such as pyridine derivatives, amines, boranes, chlorosilane, elemental selenium, and α,β-unsaturated esters. Reaction of1with pyridine, pyridineN-oxide, 2-methylpyridineN-oxide,p-toluidine, Ph2NH, 9-borabicyclo[3.3.1]nonane (9-BBN), PhSiH2Cl, elemental selenium, PhSeSePh, and methyl methacrylate (MMA) formed the amido pyridyl complexes [η5-1,2,4-(Me3C)3C5H2]2Th(NH-p-tolyl)(η2-C,N-C5H4N) (2), [η5-1,2,4-(Me3C)3C5H2]2Th(NH-p-tolyl)(κ2-C,O-C5H4NO) (3), and [η5-1,2,4-(Me3C)3C5H2]2Th(NH-p-tolyl)(κ2-C,O-2-MeC5H3NO) (4), diamide complexes [η5-1,2,4-(Me3C)3C5H2]2Th(NH-p-tolyl)2(5) and [η5-1,2,4-(Me3C)3C5H2]2Th(NH-p-tolyl)(NPh2) (6), amido hydrido complex [η5-1,2,4-(Me3C)3C5H2]2Th(H)[N(p-tolyl)B(C8H14)] (7), amido chloride complex [η5-1,2,4-(Me3C)3C5H2]2Th(Cl)[N(p-tolyl)SiH2Ph] (8), amido selenido complexes [η5-1,2,4-(Me3C)3C5H2]2Th[N(p-tolyl)Se–Se] (9) and {[η5-1,2,4-(Me3C)3C5H2]Th(SePh)}2[μ-N(p-tolyl)]2(10), and amido enolyl complex [η5-1,2,4-(Me3C)3C5H2]2Th[N(p-tolyl)CH2C(Me)C(OMe)O] (11). The new complexes2–3and6–11were characterized by various spectroscopic techniques including single crystal X-ray diffraction. Furthermore, density functional theory (DFT) studies complement the experimental investigations.
