Tóm tắt
A new iron‐organic framework, VNU‐22 {[Fe3(BTC)(BPDC)2]·11.97H2O}, constructed from BTC3–, BPDC2– pillars and infinite [Fe3(CO2)7]∞ rod SBU, was obtained. The VNU‐22 was utilized as a heterogeneous catalyst in the synthesis of 2,4,6‐triphenylpyridines via cascade reactions from acetophenones and phenylacetic acids with ammonium acetate as a nitrogen source. This transformation is new. The VNU‐22 was more active in the cascade reactions than many homogeneous and heterogeneous catalysts. The framework catalyst was recovered and reutilized without an appreciable decline in its performance. To our best knowledge, this synthetic pathway to 2,4,6‐triphenylpyridines was not previously reported, and would attract interests from the chemical industry.
