A metal–organic framework Fe3O(BPDC)3 was synthesized, and used as a productive heterogeneouscatalyst for the direct C–N coupling of azoles with ethers via oxidative C–H activation to produce azolederivatives. The MOF-based catalyst displayed higher catalytic efficiency than many homogeneouscatalysts as well as several MOFs in the transformation. The MOF-based catalyst could be reused manytimes for the synthesis of azole derivatives by the direct C–N coupling of azoles with ethers without anoteworthy deterioration in catalytic efficiency. To the best of our knowledge, this direct C–N couplingreaction was not previously performed in the presence of heterogeneous catalysts.

Iron-organic framework Fe3O(BPDC)3 was synthesized, and subsequently utilized as an productive heterogeneous catalyst for the cyclization reaction of N,N-dialkylanilines with ketoxime carboxylates to produce aryl-substituted pyridines. This iron-organic framework catalyst demonstrated remarkably higher catalytic productivity for the synthesis of aryl-substituted pyridines as compared to numerous conventional homogeneous catalysts as well as MOF-based catalysts. It was possible to reuse the iron- framework catalyst in the cyclization transformation for numerous cycles without a noticeable decline in activity. To our best knowledge, this is the first heterogeneous catalytic approach towards the synthesis of aryl-substituted pyridines from ketoximes.
