Acidity Constants of Boronic Acids as Simply as Possible: Experimental, Correlations, and Prediction

Molecules
The wide use of boronic compounds, especially boronic acids and benzoxaboroles, in virtually all fields of chemistry is related to their specific properties. The most important of them are the ability to form cyclic esters with diols and the complexation

Effect of Substituted Pyridine Co-Ligands and (Diacetoxyiodo)benzene Oxidants on the Fe(III)-OIPh-Mediated Triphenylmethane Hydroxylation Reaction

Molecules
Iodosilarene derivatives (PhIO, PhI(OAc)2) constitute an important class of oxygen atom transfer reagents in organic synthesis and are often used together with iron-based catalysts.

β‑Diketiminato Organolead Complexes: Structures, ²⁰⁷Pb NMR, and Hammett Correlations

, 2015
The synthesis, structure, and spectroscopic details of a series of β-diketiminato lead­(II) alkyl complexes are described. The Hammett correlation between the 207Pb NMR chemical shifts and σpara Hammett constant was examined computationally and found to ...

Magnetic analysis (NICS) of monoarylic cations. Linear relationship between aromaticity and Hammett constants (σp+)

, 2001
Density Functional Theory (DFT) calculations show that there is a linear correlation between NICS values (aromaticity criterion) and experimental Hammett (Brown) constants (σp+), together with other computed parameters for p-substituted benzyl cations. ©

Dissociative Electron Transfer to N‐(Arylthio)phthalimides: Factors Affecting the Formation and Dissociation of Radical Anions

ChemElectroChem
A series of chemically and biologically relevant N‐(arylthio)phthalimides is synthesized and its electrochemical reduction investigated. The results of the electrochemical study are analysed through application of Savéant's dissociative electron transfer
