| 中文摘要 | the n,n-bidentate ligand 2-{(n-2,6-diisopropylphenyl)iminomethyl)}pyrrole (l-1) and the n,n,p-tridentate ligand 2-{(n-2-diphenylphosphinophenyl)iminomethyl)}pyrrole (l-2) have been prepared. their reactions with homoleptic yttrium tris(alkyl) compound y(ch2sime3)(3)(thf)(2) have been investigated. treatment of y(ch2sime3)(3)(thf)(2) with 1 equiv of l-1 generated a thf-solvated bimetallic (pyrrolylaldiminato)yttrium mono(alkyl) complex (1) of central symmetry. in this process, l-1 is deprotonated by metal alkyl and its imino cn group is reduced to c-n by intramolecular alkylation, generating dianionic species that bridge two yttrium alkyl units in a unique eta(5)/eta(1):kappa(1) mode. the pyrrolyl ring behaves as a heterocyclopentadienyl ligand. reaction of y(ch2sime3)(3)(thf)(2) with 2 equiv of l-1 afforded the monomeric bis(pyrrolylaldiminato)yttrium mono(alkyl) complex (2), selectively. amination of 2 with 2,6-diisopropylaniline gave the corresponding yttrium amido complex (3). in 3 the pyrrolide ligand is monoanionic and bonds to the yttrium atom in a eta(1):kappa(1) mode. the homoleptic tris(eta(1):kappa(1)-pyrrolylaldiminato)yttrium complex (4) was isolated when the molar ratio of l-1 to y(ch2sime3)(3)(thf)(2) increases to 3:1. reaction of l-2 with equimolar y(ch2sime3)(3)(thf)(2) afforded an asymmetric binuclear complex (5). |
