| 中文摘要 | anilido phosphinimino ancillary ligand h2l1 reacted with one equivalent of rare earth metal trialkyl [ln{ch2si(ch3)(3)}(3)(thf)(2)] (ln = y, lu) to afford rare earth metal monoalkyl complexes [l(1)lnch(2)si(ch3)(3)(thf)] (1a: ln = y; 1b: ln = lu). in this process, deprotonation of h2l1 by one metal alkyl species was followed by intramolecular c-h activation of the phenyl group of the phosphine moiety to generate dianionic species l-1 with release of two equivalnts of tetramethylsilane. ligand l-1 coordinates to ln(3+) ions in a rare c,n,n tridentate mode. complex 1a reacted readily with two equivalents of 2,6-diisopropylaniline to give the corresponding bis-amido complex [(hl1)lny(nhc(6)h(3)ipr(2)-2,6)(2)] (2) selectively, that is, the c-h activation of the phenyl group is reversible. when 1a was exposed to moisture, the hydrolyzed dimeric complex [{(hl1)y(oh)}(2)](oh)(2) (3) was isolated. treatment of [ln{ch2si(ch3)(3)}(3)-(thf)(2)] with amino phosphine ligands hl2-r gave stable rare earth metal bisalkyl complexes [(l2-r)ln{ch2si(ch3)(3)}(2)(thf)] (4a: ln=y, r=me; 4b: ln=lu, r=me; 4c: ln=y, r=ipr; 4d: ln=y, r=ipr) in high yields. no proton abstraction from the ligand was observed. amination of 4a and 4c with 2,6-diisopropylaniline afforded the bis-amido counterparts [(l2-r)y(nhc(6)h(3)ipr(2)-2,6)(2)(thf)] (5a: r=me; 5b: r=ipr). |
