for synthesis of tertiary amides from readily available tertiary amines and anhydrides in the presence of FeCl2 as catalyst and tert-butyl hydroperoxide in water (T-Hydro) as oxidant. Mechanistic studies indicated that the in situ-generated α-amino peroxide of tertiary amine and iminium ion act as key intermediates in this oxidative transformation.

[Cu2(EDB)2(BPY)] was synthesized and used as a heterogeneous catalyst for the direct oxidative amidation between N,N‐dimethylanilines and anhydrides to form tertiaryamides as the principal products. The [Cu2(EDB)2(BPY)] exhibited similar activity as compared to that of [Cu2(BDC)2(BPY)], [Cu2(BDC)2(DABCO)], MOF‐143, and other common homogeneous salt catalysts. The optimal reaction conditions employed were [Cu2(EDB)2(BPY)]
