Heterogeneous copper-catalyzed heterocyclization between 2-iodoanilines and 2-bromothiophenols has been developed for the assembly of substituted phenothiazines.
Iron-catalyzed hydrogen production from water-promoted E-selective transfer hydrogenation. 24 substrates explored. Mechanistic insights: DFT calculation applicable to synthesis of 1,2-dideuterioalkenes.
Orthogonal chemoselective cross-coupling for C–N and C–O bond formation in amino alcohols.
Cu(II)-catalyzed robust efficient in-water N-arylation of electron-poor NH-heterocycles is reported. Wide substrate scope, decent yields, functional group tolerance, gram-scale synthesis, synthetic elaboration, late-stage arylation mirror advantages.
Copper(I) complexes stabilised by PNO-type ligands showed excellent catalytic activity for the N-arylation of indoles and carbazoles, and in the N-alkylation of indoles, via in situ generated copper nanoparticles.
