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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2799-16-8. Safety of (R)-1-Aminopropan-2-ol.
