Design of new tripodal ligands to advance the biomimetic Zinc chemistry
… properties. Several zinc complexes of three new tripodal ligands that deal with these aspects have been synthesised. First, a water soluble tripodal ligand, (2-pyridylmethylamino)-3-(3,5-dimethylpyrazol-1-yl)-propionic acid (L1H) was synthesised. With this amino acid ligand seven zinc complexes …

Zinc enzyme model complexes with Ligands containing a N2S Donor Set and their methylating reactions
A new tridentate and two new tripodal ligands containing a N2S donor set have <br>been prepared in this work. These and other four selected ligands together with <br>different thiolate co-ligands have been used for the syntheses of 47 new zinc <br>enzyme model complexes. These complexes have been …

Novel Group 4 Metal Amido Complexes - syntheses, reactivity and olefin polymerization catalysis
… functionalized electron rich aminopyridinato ligands was synthesized by the methodology developed by Fort and coworkers and subsequent Ulmann thermal amination. In addition to this some tripodal ligands containing nitrogen donor functionalities were also synthesized. The corresponding titanium …

Metallo-supramolecular Architectures based on Multifunctional N-Donor Ligands
… was the design of multifunctional N-donor ligands and the characterization of their complexing and structural properties. This work was divided into three distinct main parts: The bis(2-pyridylimine), the bis(2-hydroxyaryl) imine and the tripodal imine / amine ligand approach. In the first …

Chemistry and biology of tricarbonyl complexes of technetium and rhenium
Chapter One: Two of the most famous tripodal ligands, Kliui's cyclopentadienyltris(dialkylphosphito)cobaltate(III) and Trofimenko's hydrotris(1-pyrazolyl)borate, were studied with respect to their reactivity towards Alberto's tris(solvento)tricarbonyltechnetium(I) and …

Two approaches to the design and synthesis of bimetallic complexes
… was gained from a pair of H bonds between two ligands facing each other. The phenomenon was observed for all ligands but N, N’ -bis(2,6-dimethylphenyl)formamidine ( L2 ), in which ligands in Z conformation were connected through H bonds from both sides of a ligand and an infinite chain …

Tris-Pyridyl Ligands and Beyond: Modifications Derived from the Bridgehead and Donor Vector
Abstract Tris-Pyridyl Ligands and Beyond: Modifications Derived from the Bridgehead and Donor Vector – Jessica Ellen Waters The development of new classes of ligands is a fundamental and ongoing challenge in modern chemistry, and a cornerstone in modern catalysis, supramolecular assembly and …

Auxiliary proton-influenced metal-mediated reactions: dioxygen activation, anion coordination, and catalysis
… blocks allow the preparation of tridentate N3 ligands decorated with OH and OMe substituents flanking the fourth coordination site of a tetrahedral complex. Crystallographic characterization of the ligand complemented with two methyl and one OH group revealed that it exists as the pyridone …

(I) Zinc complexes as synthetic analogues for carbonic anhydrase and as catalysts for H₂ production and CO₂ functionalization . . .
… an organometallic counterpart to the more common tripodal ligands, [Tp] ([Tp] = tris(pyrazolyl)hydroborato) and [Tm] ([Tm] = tris(2-mercaptoimidazolyl) hydroborato). A wide range of [Tptm] zinc complexes have been synthesized, enabling a diverse range of both stoichiometric and catalytic chemical …
