Structure and Photophysical Properties of 2,6-Di-tert-Butyl-4-arylpyrylium 2-Naphthalenesulfonate Ion Pairs in Solution and in the Solid State

2,6-Di-tert-butyl-4-arylpyrylium 2-naphthalenesulfonate salts form ion pairs in dimethylcarbonate solution that exhibit charge-transfer absorptions and result in the rapid quenching of the pyrylium fluorescence.Molecular mechanics calculations predict that these ion pairs exist in a T-shaped orientation, but X-ray structural analysis reveals a ? face-to-face arrangement in the solid state.Nuclear Overhauser effect and time-resolved spectroscopic experiments carried out in solution are consistent with a T-shape for the ion pair, but these experiments do not prove that this structural hypothesis is correct.
I2-mediated oxidative C-N bond formation for metal-free one-pot synthesis of di-, tri-, and tetrasubstituted pyrazoles from α,β-unsaturated aldehydes/ketones and hydrazines

An I2-mediated metal-free oxidative C-N bond formation methodology has been established for the regioselective pyrazole synthesis. This practical and eco-friendly one-pot protocol requires no isolation of the less stable intermediates hydrazone
