Synthesis, structure and catalytic activity of rare-earth metal amino complexes incorporating imino-functionalized indolyl ligand
The reactions of the imino-functionalized indolyl ligand (HL, L = 3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5N) with the rare-earth metal amides [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) producing different types of rare-earth metal amido complexes were investigated. The reactions of HL with 1 equiv. of [(Me3Si)(2)N](3)RE(mu-Cl)Li(THF)(3) generated a series of hetero-nuclear bimetallic rare-earth metal amino complexes {[eta(1):mu-eta(2)-3-(4-Me2N-C6H4CH=N-CH2CH2)C-8 H-5]RE[N(SiMe3)(2)](2)(mu-Cl)Li(THF)} (RE = Y(1 ), Sm(2), Gd(3), Er(4), Yb(5)). By extending the reaction time, only the reaction of HL with [(Me3Si)(2)N](3)Gd(mu-Cl)Li(THF)(3) gave an unexpected binuclear rare-earth metal complex {[(mu-eta(5) :eta(1)):eta(1):eta(1)-3-[(Me2N)(2)-C14H9]-(NCH2CH2-C8H5N)(2)]Gd-2[N(SiMe3)(2)](3)} (6 ) incorporating a novel polycyclic ligand through C-C and C-N coupling. Treatment of HL with [(Me3Si)(2)N](3)Sm(mu-Cl)Li(THF)(3) in a 2:1 ratio generated the bis(indolyl) heteronuclear bimetallic rare-earth metal amino complex {(eta(1):eta(1)-[mu eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5]Li[mu-eta(2):eta(1)-3-(4-Me2N-C6H4CH=N-CH2CH2)C8H5])Sm[N(SiMe3)(2)](2)} (7) in low yield probably due to accompanying with the formation of the complex 2 . The above results indicated that reaction conditions play important roles in the formation of different coordination modes of the imino-functionalized indolyl rareearth metal amido complexes. All new complexes 1-7 are fully characterized including X-ray structural determination. The catalytic activity of complexes 1 7 for the addition of amines to carbodiimides was explored. The results showed that all complexes displayed an excellent activity towards the addition of amines to carbodiimides producing guanidine under solvent-free condition. (C) 2020 Elsevier B.V.
