| 英文摘要 | New imido-carboranes 1-(CH=NC6H3R2-2,6)-1,2-C2B10H11 (R = Pr-i (3a), Me (3b)) were successfully prepared by Schiff base condensation of 1-CHO-1,2-C2B10H11 with R2C6H3NH2. They were readily converted into the corresponding imido-dicarbollyl ligands 7-(CH=NHC6H3R2-2,6)-7,8-C2B9H11 (R = Pr-i (4a), Me (4b)) by refluxing in dry MeOH. Treatment of 3a with Ti(NMe2)(4) in hot toluene gave a constrained-geometry complex, [eta(1):eta(5)-((Pr2C6H3N)-Pr-i=CH)C2B9H10]Ti(NMe2)(2) (5a). Under the same reaction conditions, interaction of 3b with Ti(NMe2)(4) produced a mixture of [eta(1):eta(5)-(Me2C6H3N=CH)C2B9H10]Ti(NMe2)(2) (5b) and [eta(1):eta(5)-(Me2N)CH(NMe2)(C2B9H10)Ti(NMe2)(2) (8). Reaction of 4a with M(NMe2)(4) in toluene/DME at room temperature afforded 5a and [eta(1):eta(5)-((Pr2C6H3N)-Pr-i=CH)C2B9H10]M(NMe2)(2)(NHMe2) (M = Zr (6a), Hf (7a)), respectively. Complexes 5a, 6a, and 7a were active catalysts for the polymerization of ethylene in the presence of MMAO with activities of 3-16 kg/mol.h.atm. These new complexes were fully characterized by various spectroscopic techniques and elemental analyses. The molecular structures of 3a, 3b, 4a, 5a, 5b, 6a, 7a, and 8 were further confirmed by single-crystal X-ray analyses. |
