Abstract: An approach for the synthesis of new organic ligands combining in their structure pyridine, benzothiazole, and polyethylene glycol fragments was developed, proceeding from 6-hydroxy-2-(pyridin-2-yl)benzothiazole and mono- or ditosyl-substituted polyethylene glycols. The ligand 2-(2-{[2-(pyridin-2-yl)benzothiazol-6-yl]oxy}ethoxy)ethanol (L) in… read more here.

Abstract: Recently, we introduced the first example of chiral-at-iron catalysts in which two achiral N-(2-pyridyl)-substituted N-heterocyclic carbene (NHC) ligands in addition to two labile acetonitriles are coordinated around a central iron, to generate a stereogenic metal… read more here.

Abstract: Pyridyl-substituted triarylmethyl radicals exhibited cation-responsive turn-on fluorescence when additional pyridyl rings were incorporated at an appropriate position; the mechanism of fluorescence enhancement is examined. Reduced quenching by internal and external heavy atom effects is proposed… read more here.
