Stereoselective Chiral Recognition of Amino Alcohols with 2,2′-Dihydroxybenzil

2,2′-Dihydroxybenzil is demonstrated to be a highly diastereoselective stereodynamic receptor for the chiral recognition of amino alcohols. The receptor by forming diimine compounds with amino alcohols showed good (11:1) to excellent (>50:1) diastereoselectivity in chloroform. The existence of intramolecular hydrogen bonding with amino alcohols only in an axial conformer is demonstrated by 1H NMR and CD spectroscopy, X-ray crystallography, and DFT computations. The exciton chirality method can be used with diazo-attached 2,2′-dihydroxybenzil.

On the non-innocence and reactive: Versus non-reactive nature of α-diketones in a set of diruthenium frameworks

α-Diketones are an important class of building blocks employed in many organic synthetic reactions. However, their coordination chemistry has rarely been explored. In light of this, our earlier report on [(acac)2RuII(μ-2,2′-pyridil)RuII(acac)2] (acac = acetylacetonate) showcased the sensitivity of a diketone fragment towards oxidative C-C cleavage. Following the lead, the synthesis of similar but stable diketo fragments containing diruthenium compounds was attempted. Three diruthenium compounds with the bridge 1,2-bis(2-hydroxyphenyl)ethane-1,2-dione (L) were prepared: diastereomeric [(acac)2RuIII(μ-L2-)RuIII(acac)2], 1a(rac)/1b(meso), [(bpy)2RuII(μ-L2-)RuII(bpy)2](ClO4)2, [2](ClO4)2 and [(pap)2RuII(μ-L2-)RuII(pap)2](ClO4)2, [3](ClO4)2 with ancillary ligands of different donating/accepting characteristics. The metal is stabilised in different oxidation states in these complexes: Ru(iii) is preferred in 1a/1b when σ-donating acac is used as the co-ligand whereas electron rich Ru(ii) is preferred in [2](ClO4)2 and [3](ClO4)2 when co-ligands of moderate to strong π-Accepting properties are employed. The oxidative chemistry of these systems is of particular interest with respect to the participation of varying bridging-ligands which contain phenoxide groups. On the other hand, the reduction processes primarily resulting from the metal or the ancillary ligands are noteworthy as the normally reducible 1,2-diketo-group remains unreduced. These results have been rationalised and outlined from thorough experimental and theoretical investigations. The results presented here shed light on the stability of metal coordinated α-diketones as a function of their substituents.

2,2′-dihydroxybenzil: A stereodynamic probe for primary amines controlled by steric strain

A rational approach for generating 1,1′-binaphthalene-like axial chirality of a small organic receptor, 2,2′-dihydroxybenzil is presented. The receptor combines with 2 equiv of monodentate primary amines to form a diimine, of which axial chirality is controlled by steric strain with moderate (1.4:1) to good (4.7:1) stereoselectivity. The observed circular dichroism (CD) spectra have been closely simulated by TD-DFT computations and can be used for determining the absolute chirality and enantiomeric excess of primary amines.

Design, synthesis, and characterization of novel organic-inorganic hybrid polymeric materials for electroluminescence applications

We have designed and synthesized a novel heteroatomic, multidentate, Schiff's base, and di-anionic ligand for the fabrication of two new electroluminescent polymeric materials. All the newly synthesized materials are redox-active, and both polymers show reversible electroluminescence on the application of an appropriate potential.

Highly selective recognition of fluoride anion through direct deprotonation of intramolecularly hydrogen-bonded phenolic hydroxyl groups

A novel chemosensor for fluoride anion has been developed. This sensor, constructed by merging six phenolyl units into a hexaazatriphenylene (HAT) core, could recognize F- visually and spectroscopically with high selectivity over other anions,
