The use of formic acid or carbon dioxide as a C1 source for the synthesis of medicinally, as well as industrially, imperative compounds has been gaining predominant attention of synthetic chemists in the current era. This article describes the synthesis of an eco-friendly low-cost modified Merrifield supported zinc catalyst [Zn(Meri-Ald-Py)]. Characterization of the newly synthesized catalyst was performed properly by various instrumental techniques like CHN analysis, elemental mapping, FTIR, Energy Dispersive X-ray analysis, FESEM, TGA, PXRD, N₂ adsorption–desorption and AAS (atomic absorption spectroscopy). Benzimidazolone derivatives were synthesized quite efficiently through CO₂ fixation in o-phenylenediamine in the presence of a Zn(Meri-Ald-Py) catalyst at 110 °C using 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) under atmospheric pressure. Furthermore, the synthesized catalyst can effectively produce various N-formylated products from aniline derivatives by utilizing formic acid within a very short reaction duration (4.5–20 minutes) at 30 °C. Above all, the catalyst is highly heterogeneous in nature and can be used proficiently in several successive cycles.

在锌包埋的聚合物络合物存在下，使用甲酸通过CO 2固定和N-苯基甲酰胺合成苯并咪唑酮

在当今时代，使用甲酸或二氧化碳作为C1来源来合成医学以及工业上必不可少的命令性化合物已成为合成化学家的主要关注点。本文介绍了一种环保型低成本改性Merrifield负载型锌催化剂[Zn（Meri-Ald-Py）]的合成。新合成的催化剂的表征通过各种仪器技术正确进行，例如CHN分析，元素图谱，FTIR，能量色散X射线分析，FESEM，TGA，PXRD，N ₂吸附-解吸和AAS（原子吸收光谱法）。苯并咪唑酮衍生物通过在水中固定CO ₂相当有效地合成-苯二胺在Zn（Meri-Ald-Py）催化剂的存在下，在大气压下使用1,8-二氮杂双环[5.4.0]十一碳-7-烯（DBU）在110°C下存在。此外，通过在30°C的极短反应时间（4.5-20分钟）内利用甲酸，合成的催化剂可以有效地从苯胺衍生物生产各种N-甲酰化产物。最重要的是，该催化剂本质上是高度多相的，可以在几个连续的循环中充分使用。
