Due to their unique properties, polythiophene and other conductive polymers have become the subject of intensive research are promising substrate materials for innovative trendsetting applications. To this day, boron trifluoride diethyl etherate (BFEE) is preferred solvent electropolymerization thiophene, although it does not allow reproducible film qualities due its decomposition under ambient...

A one-pot procedure is described for using alpha,beta-unsaturated aldehydes as olefin equivalents in the Diels-Alder reaction. The method combines the normal electron demand cycloaddition with aldehyde dienophiles and the rhodium-catalyzed decarbonylation of aldehydes to afford cyclohexenes with no electron-withdrawing substituents. In this way, the aldehyde group serves as a traceless control ...
