Syntheses of sterically hindered zwitterionic pyridinium phenolates as model compounds in nonlinear optics

Pyridinium phenolates possess a dissymmetric delocalised π-electron system providing a huge quadratic nonlinearity. They are a promising class of molecules for applications in photoelectronics and photonics. Semiempirical calculations indicate that the interplanar angle between the two aromatic rings leads to enhancement in the NLO properties of these compounds. The confirmation of this feature may be provided by the study of a new series of sterically hindered pyridinium phenolates 2a-e bearing two tert-butyl substituents at the ortho position(s) of the phenolate functionality. Such bulky groups would enhance the solubility of zwitterions in organic solvents and would limit the formation of aggregates. Their efficient preparations by using Suzuki cross-coupling reactions involving 3,5-dialkylated 4-bromopyridine N-oxides are described herein. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Theory and Experimental Illustration of Preparative Electrochemistry Using Redox Catalysis of Electron Transfer Initiated Radical Chain Reactions. Application to the Cross-Coupling between Aryl Halides and Phenoxide Ions

A general equation predicting the yield of electron transfer initiated radical chain reaction (SRN1 and related mechanisms) under preparative electrochemical conditions is given for situations where the electron-transfer activation of the chain is performed by means of a redox mediator.Simple tests, allowing for the choice of proper redox mediator, are given, and their origins established and discussed.The validity and application of this simple model is shown and discussed for the case of the SRN1-like reaction involving di-tert-butylphenoxide as a nucleophile, to afford biaryls of interest for their properties in nonlinear optics.
