Selective electrochemical and photochemical syntheses of unsymmetrical biaryls and their non-linear optical properties

Abstract

A selective synthesis of unsymmetrically substituted electron donor/electron acceptor biaryls is described which is based on an electrochemically or photochemically induced S_RN1 reaction; the optical hyperpolarizability coefficients β are determined in solution for the various reaction products and found to be of the same order of magnitude as that of 4-nitro-aniline.
