Anion‐Templated Assembly of Half‐Sandwich Rhodium‐Based Multinuclear Metallamacrocycles

Chemistry – A European Journal, 2011
AbstractA series of half‐sandwich rhodium‐based metallamacrocycles with tetra‐ and hexanuclearities have been synthesized. They are assembled by linking the deprotonated 2,4‐diacetyl‐5‐hydroxy‐5‐methyl‐3‐(3‐pyridinyl)cyclohexanone (HL) ligand in the presence of counteranions.

Novel 48-Membered Hexadecanuclear and 60-Membered Icosanuclear Manganese Metallamacrocycles

Inorganic Chemistry, 2008
Either an S 8 symmetrical 48-membered hexadecanuclear or an S 10 symmetrical 60-membered icosanuclear manganese metallamacrocycle was self-assembled using a manganese ion and a ditopic pentadentate ligand. This was either N-4-phenylbenzoylsalicylhydrazide (H 3pbshz) containing a rigid rod-shaped, bulky biphenyl residue as a terminal N-acyl group or N-3,

Reaction of a Metallamacrocycle Leading to a Mercury(II)⋅⋅⋅Palladium(II)⋅⋅⋅Mercury(II) Interaction

Angewandte Chemie, 2009
AbstractMetallophile Wechselwirkung: Ein aus Bis(o‐formylphenyl)quecksilber und 1,2‐Phenylendiamin erhaltener, 22‐gliedriger Makrocyclus reagiert mit Palladium(II) unter Spaltung des Makrocyclus und gleichzeitiger Bildung eines Trimetallkomplexes (siehe Bild; die Phenylringe sind nur ausschnittsweise gezeigt).

Half-sandwich rhodium and iridium metallamacrocycles constructed via C–H activation

Dalton Transactions, 2016
One- or two-site C–H activation of unsymmetrical and symmetrical proligands is employed to prepare a range of rectangular metallomacrocycles with a range of isomers. The CO2adsorption of the complexes was studied, and the symmetrical, rigid ligand systems showed the best performance.

Three-Dimensional Helical Coordination Networks of a Hexanuclear Manganese Metallamacrocycle as a Helical Tecton

Inorganic Chemistry, 2004
We report on helical coordination networks that were prepared using a hexanuclear manganese metallamacrocycle as a helical tecton. We were able to prepare the three-dimensional helical coordination networks using a hexanuclear manganese metallamacrocycle, [Mn(6)(lshz)(6)], as a helical tecton, where N-lauroyl salicylhydrazide (H(3)lshz) was used as the

Self-Assembly of Metallamacrocycles via a Rigid Phosphorus Donor Linker

Organometallics, 2007
The coordination-driven self-assembly of a series of discrete 2D metallomacrocycles from a rigid diphosphine donor linker and Pd/Pt-containing 90° acceptors is described. All these assemblies are characterized by multinuclear NMR and, in four cases, X-ray crystallography.

Specific recognition of fluoride anion using a metallamacrocycle incorporating a uranyl-salen unit

New Journal of Chemistry, 2008
The design and synthesis of a novel fluoride receptor that uses a salen-complexed Lewis acidic uranyl center as the sole binding site is reported here. This receptor binds fluoride anions in DMSO with a high affinity constant (K > 106 M-1) and exhibits a negligible affinity (K < 10 M-1) towards otherwise effective competitors, such as acetate ...

Bisphosphine ligands, metallamacrocycles and a solid-supported alkene metathesis catalyst

2003
The aim of this work was to develop a solid-supported alkene metathesis catalyst. The initial strategy involved two new bisphosphine ligands, DPEN I and DPPN II, and the short and efficient syntheses of these ligands from 2,7-dihydroxynaphthalene are described. The platinum, palladium and ruthenium complexes of ligands I and II were investigated.
