Extension studies on iron(III)-promoted free radical oxidation of anilines: self-coupling and self-bridged assembling reactions
摘要:
The iron(III)-promoted free radical oxidation of anilines has been further developed. Anilines including those bearing strong electron-withdrawing groups on benzene ring were readily converted into corresponding self-coupling benzidines. With addition of base, the methyl on nitrogen was activated and the free radical oxidations tended to furnish the corresponding self-bridged assembling diaminodiarylmethanes. (C) 2015 Elsevier Ltd.

The first example of room temperature non-noble metal homogeneous system catalyzedselective N-alkylation of anilines with alcohols by a bis-NHC manganese complex is presented. This system was applied to a large range of alcohols and anilines, including biologically relevant motifs and challenging methanol. Experimental and computational studies suggest an outer-sphere mechanism for this NHC–Mn system

dispersed active Ir(I) centers and the large π-conjugation rings endow the solid catalysts with an exceptionally high activity and selectivity for a broad substrate scope. Such solid NHC-Ir coordination assemblies are robust, which can be easily recovered and reused more than 10 runs without significant loss of their catalytic activity and selectivity. When combined with a subsequent formylation using the same
