| 中文摘要 | treatment of yttrium tris(alkyl)s, y(ch2sime3)(3)(thf)(2), by equimolar h(c5me4)sime3(hcp') and indene (ind-h) afforded (eta(5)-cp')y(ch2sime3)(2)(thf) (1) and (eta(5)-ind)y(ch2sime3)(2)(thf) (2) via alkane elimination, respectively. complex 1 reacted with methoxyamino phenols, 4,6-(ch3)(2)-2-[(meoch2ch2)(2)-nch2]-c6h2-oh (hl1) and 4,6-(cme3)(2)-2-[(meoch2ch2)(2)-nch2]-c6h2oh (hl2) gave mixed ligands supported alkyl complexes [(eta(5)-cp')(l)]y(ch2sime3) (3: l = l-1; 4: l = l-2). whilst, complex 2 was treated with hl2 to yield [(eta(5)-ind)(l-2)]y(ch2sime3) (5). the molecular structures of 3 and 5 were confirmed by x-ray diffraction to be mono(alkyl)s of thf-free, adopting pyramidal and tetragonal-bipyramidal geometry, respectively. complexes 3 and 5 were high active initiators for the ring-opening polymerization of l-lactide to give isotactic polylactide with high molecular weight and narrow to moderate polydispersity. |
