Abstract:

Reaction between 2,6-bis(2-formylphenoxymethyl)pyridine and N,N-bis(3-aminopropyl)methylamine or tris(2-aminoethyl)amine has been used as the starting point for the synthesis of seven oxa-aza macrocyclic ligands, five of them never reported previously. They all feature different pendant arms, which provide a wide range of coordination possibilities. The Schiff base macrocycles L1 and L4 and their reduced ligands L2 and L5 are derived from 2,6-bis(2-formylphenoxymethyl)pyridine and tris(2-aminoethyl)amine or N,N-bis(3-aminopropyl)methylamine, respectively. The reaction of L1 with salicylaldehyd

Ten complexes of the type [RuCl2(L1-10)] (where L= macrocyclic Schiff base ligands) have been synthesized by reaction of [RuCl2(DMSO)4] with ten macrocyclic Schiff base ligands. These complexes were characterized by elemental analysis, molar conductance; UV-Visible spectra, IR, magnetic movement and X-ray photoelectron spectra (XPS). An octahedral geometry was established for all these complexes.

Abstract:

The synthesis of five 20-membered, N-benzylated macrocyclic ligands incorporating N4O2-donor sets and from one to three benzyl substituents for use in metal-ion recognition studies is described. The new derivatives were obtained by both benzylation of the pre-formed parent macrocycle using benzyl chloride in acetonitrile in the presence of base or, in one case, by performing macrocyclic ring closure using the appropriate N-benzylated triamine precursor by means of a bis-Schiff base condensation with the corresponding dialdehyde, followed by in situ reduction of the diamine linkages so formed.

Reported here is the synthesis of new binuclear rhodium(III) and iridium(III) semi-sandwich complexes of a Schiff-base expanded porphyrin. Single crystals of these new complexes were subject to X-ray diffraction analysis. The resulting structures revealed that the Schiff-base macrocycle adopts a V-shape in which two {(η5- C 5 Me 5) MCl } ( M = Rh and Ir ) fragments are accommodated within the macrocyclic pocket. The coordination environment of the metal centers is typical to that of "piano stool"-type complexes. The X-ray analyses and complementary NMR studies (carried out in CD 2 Cl 2) provid

Abstract:

With the goal of developing Schiff base macrocycles with conjugation extended over multiple aromatic rings, new phenanthrene and triphenylene-containing bis(salicylates) were synthesized. A convenient route to 3,6,9,10-tetraalkoxy-2,7-diiodophenanthrene was developed. This compound has been found to be a useful precursor for Pd-catalyzed cross-coupling reactions. Macrocycles were synthesized by Schiff base condensation of the phenanthrene and triphenylene precursors. Reaction of smaller phenanthrene and triphenylene bis(salicylates) with 1,2-dialkoxy-4,5-phenylenediamine afforded macrocycles

Abstract:

Conjugated Schiff-base macrocycles are interesting compounds of interest as platforms for catalysis, the preparation of novel synthetic ion channels and potentially as porous or tubular discotic liquid crystals. The preparation of organic macrocycles is typically low yielding, with polymerization competing with cyclization; the use of imines derived from the condensation of an aldehyde and an amine provides a means by which to conduct cyclizations under thermodynamic control and thereby improve yields. The use of difunctional aldehydes and amines allows for the formation of macrocycles in high
