Investigations into Cu-catalyzed methods for C(sp2)-N-couplings of hydantoins at both nitrogen atoms (Master thesis / Masteroppgave, 2022)N,N’-Diarylated hydantoins have previously been difficult to synthesize and a method for a direct N,N’-diarylation does not exist. This thesis describes a carefully investigated one-pot N,N’-diarylation reaction of hydantoin, ...
