The synthesis of a new ligand, H3BBAC (N,N-bis(2-hydroxybenzyl)aminoacetic acid) and its first VIVO2+ complex, [Et3NH]2[O=V(BBAC)]2 (1), are presented in order to model the active site of vanadium tra

Reported examples of aggregated initiators for the ring-opening polymerisation (ROP) of lactide often lack detailed investigations as to the nature of the active species, making it difficult to reconcile ligand design with performance. Here, we offer addi

Five new ternary iron(III) complexes with phenolate-based ligands of general molecular formula, [Fe(L1)B] and [Fe(L2)B], where L1 = 2-(bis(2-hydroxybenzyl)amino)acetic acid, L2 = 2-bis[3,5-di(tert-butyl)-2-hydroxybenzyl]aminoacetic acid, B = phen (1,10-phenanthroline), ip (1H-imidazo[4,5-f ][1,10]phen-anthroline) and pyip (2-(pyren-1-yl)-1H-imidazo[4,5-f ][1,10]-phenanthroline) were synthesized and probed for visible light-induced cytotoxicity in human cervical carcinoma (HeLa) cells. The complexes in generating hydroxyl radicals from molecular oxygen on visible light-induced phenolate(O)?Fe(III) or carboxylate(O)?Fe(III) charge transfer prompted apoptosis in HeLa cells with IC50 values in the range of 4.624.3 ˉM while remaining non-toxic in dark.

The synthesis and full characterisation of four discrete tetrametallic titanium complexes is reported. These well-defined compounds are isostructural in the solid state and share the same general formula: Ti4(μ-O)2L4 (L = 1, 2, 3 or 4). Using a combination of NMR techniques the complexes are found to be stable in solution, even at elevated temperatures. Further studies show that the carboxylate moieties of the supporting amine bis(phenolate) ligands can be displaced by a more strongly coordinating solvent. This reversible process causes the coordinatively saturated Ti4(μ-O)2L4 complexes to separate into two Ti2(μ-O)L2 subunits which we envisaged would be catalytically active. Proof-of-concept experiments establish that all four of these complexes display catalytic activity in the ring-opening polymerisation of rac-lactide. These aggregates can therefore be viewed as air and moisture stable pre-catalysts for a range of reactions.
