Chemistry – A European Journal, EarlyView.Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core
Chemistry – A European Journal, EarlyView.RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Oxidation of alcohols with pyridinium bromochromate
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1996 Pyridinium bromochromate (PBC) is a versatile and inexpensive oxidizing agent. It converts different classes of alcohols to the corresponding carbonyl compounds. Primary and secondary benzylic alcohols are oxidized in moderate to high yields. Synthetic utility of the reagent has been shown to increase in the presence of glacial acetic acid for the ...

Investigating the chemistry of pyridinium ylides [PDF]
, 2018 This thesis describes investigation into catalytic formation of pyridinium ylides from diazo compounds and their subsequent reactivity. In particular, cycloaddition reactions with electrophilic alkenes are performed to generate tetrahydroindolizines that

Chemistry – A European Journal, EarlyView.Nonafluoromesitylsulfonyl (Nms)‐substituted oxycarbamates are introduced as redox‐lowered radical precursors for green‐light photoredox synthesis. Selective N─O bond cleavage generates amidyl radicals that directly aminate indolizines in DMF, whereas DMSO promotes 1,2‐hydrogen atom transfer (HAT) to α‐amino carbon‐centered radicals and C─C bond ...

The Radical Chemistry of 2,3‐Diguanidinopyridines: Coordination and Visible‐Light Photochemistry
Chemistry – A European Journal, EarlyView.Substitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.

Chemistry – A European Journal, EarlyView.A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...
