Article abstract of DOI:10.1021/je00051a024

Several N,N'-diacylated 2,2'-biphenyleneureas were synthesized by quenching the intermediate resulting from the reaction between 2,2'-biphenyleneurea and n-butyllithium with the corresponding acylating reagent.The reactions were carried out under inert at
