Clean and direct synthesis of alpha,alpha'-bithiophenes and bipyrroles by metal-free oxidative coupling using recyclable hypervalent iodine(III) reagents.
The facile and clean oxidative biaryl coupling reaction of thiophenes and pyrroles has been achieved using the recyclable hypervalent iodine(III) reagents having adamantane or methane structures. These iodine(III) reagents could be recovered from the reaction mixtures by a simple solid-liquid separation, i.e., filtration.
