Re(I) carbonyl complexes containing pyridyl-imine or amine ligands have been synthesized and crystallographically characterized. Their catalytic activity for the cis-cyclooctene epoxidation with tert-butyl hydroperoxide (TBHP) as oxidant and the oxidation of these Re(I) complexes by TBHP have been investigated.

Ascorbate is an important biological reductant and enzyme cofactor. Although direct detection through ascorbate-mediated reduction is possible, this approach suffers from poor selectivity due to the wide range of cellular reducing agents. To overcome this limitation, we leverage reduction potential of ascorbate to mediate a copper-mediated oxidative bond cleavage of ether-caged fluorophores. The copper(II) complexes supported by a {bis(2-pyridylmethyl)}benzylamine or a {bis(2-pyridylmethyl)}(2-methoxybenzyl)amine ligand were identified as an ascorbate responsive unit and their reaction with ascorbate yields a copper-based oxidant that enables rapid benzylic oxidation and the release of an ether-caged dye (coumarin or fluorescein). The copper-mediated bond cleavage is specific to ascorbate and the trigger can be readily derivatized for tuning photophysical properties of the probes. The probes were successfully applied for the fluorometric detection of ascorbate in commercial food samples, human plasma, and serum, and within live cells by using confocal microscopy and flow cytometry.

Described are metal complexes for the selective detection of ascorbic acid or ascorbate. The metal complexes act as molecular sensors, and are useful in detecting ascorbate in live biological samples, commercial samples, or both. The selective ascorbate sensing involves an ascorbate-selective bond cleavage reaction. The bond cleavage is not limited to the construction of molecular sensors, but also includes other stimuli-responsive materials, i.e., materials that adopt a physical state, such as gel formation, upon ascorbate-selective bond cleavage of the metal complexes.
