| 中文摘要 | the scandium bis(alkyl) complex bearing the phosphazene ligand (lsc)-sc-1(ch2sime3)(2) (1) (l-1 = n(pph2=nph)(2)) reacted with an equimolar amount of 2,6-diisopropylaniline to afford the corresponding mixed alkyl/anilido complex (lsc)-sc-1[nhc6h3(pr-i)(2)](ch2sime3) (2). under mild conditions (20 degrees c, 4 h or 0 degrees c, 12 h), complex 2 could be swiftly transformed to the terminal imido complex (lsc)-sc-1=n[c6h3(pr-i)(2)](dmap)(2) (4) in the presence of dmap (dmap = 4-n,n-dimethylaminopyridine). correspondingly, treatment of the yttrium and lutetium bis(alkyl) complexes l(2)ln(ch2sime3)(2) (l-2 = n [ph2pnc6h3(pr-i)(2)](2); ln = y (7), lu (8)) with equimolar amounts of 2,6-diisopropylaniline gave the mixed alkyl/anilido complexes l(2)ln[nhc6h3(pr-i)(2)](ch2sime3) (ln = y (9), lu (10)), which, however, underwent dealkylation of the ln ch2sime3 species at temperatures of 60 degrees c for 9 and 100 degrees c for 10 to afford bis(anilido) complexes l(2)ln[nhc6h3(pr-i)(2)](2) (ln = y (11), lu (12)) as redistribution products. all these complexes have been characterized by h-1, c-13{h-1}, and p-31{h-1} nmr spectroscopy and x-ray diffraction analyses, and clear structural insight into the behavior of an imido functionality on a lanthanide metal center was provided. |
