One-Pot Synthesis of Diverse 1,4-[60]Fullerephenols via Three-Component Umpolung Cascade Coupling of Phenols, C , and Nucleophiles.

A three-component umpolung cascade coupling reaction of phenols, C , and different nucleophiles which includes H O, alcohols, triphenylamines and carbazoles was developed. Furthermore, one-pot 1,4-bisphenol coupling on C has been realized by this method. This practical protocol features high chemo- and regioselectivity, wide substrate range, easy operation and low cost, thus providing a robust method for the one-pot synthesis of various unsymmetrical 1,4-[60]fullerephenols.
