Highly Conjugated Bis(benzo[b]phosphole)‐P‐oxides: Synthesis and Electrochemical, Optical, and Computational Studies

Abstract

Dedicated to Professor Cesare Gennari on the occasion of his 70 th birthdayThe first examples of a π-conjugated benzo[b]phosphole Poxide in which two phosphole P-oxide units are connected by a carbon-carbon double bond are described. The molecules are synthesized as E isomers with respect to the carbon-carbon double bond and exist as stable cis and trans isomers (chiral and meso one respectively) relatively to the two stereogenic P atoms. The optical and electrochemical properties of both isomers have been investigated by experiment and computations.
