One-Pot Three-Component Solvent-Free Syntheses of n-Alkyl-Bridged N,N,N,N-tetra(2-hydroxybenzyl)diamines and N,N-bis(2-hydroxybenzyl) amines

Oxidovanadium(V) Complexes with Aminoethanol Bis(phenolate) [O,N,O,O′] Ligands: Preparations, Structures, N‐Dealkylation and Condensation Reactions

“…[35] The purification of the ligands H 3 L1 -H 3 L3 required crystallization as hydrochlorides; thus complexation reactions were initially carried out using these hydrochlorides as ligand precursors. However, this procedure did not give satisfactory results (demonstrated later by H 3 L2), so that the ligands were mainly used as free bases after neutralization (see experimental part).…”

“…[28,35] The ligand H 3 L3·HCl was prepared as described below. For the numbering scheme of the complexes 6 and 7, see Figures 4 and 5.…”

Syntheses and Structural Study of Novel Tetranuclear Bis(phenoxido)‐Bridged CuII Metal–Organic Macrocycles

“…H 4 L1 and H 4 L2 were prepared using a known procedure. [5] X-ray crystallography, elemental and IR analyses were performed in situ after the removal of the liquid reaction medium because of the rapid decomposition of the crystalline complexes.…”

“…All studied complexes showed strong antiferromagnetic behaviour. [5] which can be used in traditional coordination chemistry but also have potential as building blocks for molecular manufacturing used to produce molecular rings and metal-organic frameworks. This area of chemistry provides limitless possibilities in the design of molecular materials possessing extraordinary sensing, magnetic, catalytic and optical properties.…”

A Combined Experimental and Theoretical Study on Bis(μ‐alkoxo)diiron(III) Complexes with Hydroxybenzylaminoethanol [O,N,O] Donor Ligands: Syntheses, Structures and Magnetic Properties

“…Ligand and Complex Synthesis: Ligands H 2 L1 and H 2 L2 were synthesized following a general procedure [13] as follows: 11 mmol of 2,4-di-tert-butylphenol, 11 mmol of paraformaldehyde and 10 mmol of the corresponding amine (N-methylethanolamine or 2-aminoethanol, respectively) were placed in a partially closed reaction vial. The vial was kept in thermal oven (120°C) and the reaction was monitored with HPLC.…”
