In this study, we report the synthesis and physicochemical characterization of a novel one-dimensional copper(II) coordination polymer ([Cu(L)₂]_n) based on 2-acetylfuranisonicotinichydrazone, as well as its catalytic activity in the liquid-phase oxidation of benzyl alcohol. Based on spectroscopic and single crystal X-ray diffraction crystallography, the Cu(II) ion is pentacoordinated, bonded to two anionic hydrazones through the N,O chelating sites, and to the N-pyridyl atom from a third ligand molecule, which provides the formation of a one-dimensional network. The coordination polymer was evaluated as homogeneous catalyst, attaining high selectivity (90.1 %) and yield (36.9 %) towards benzaldehyde under mild conditions (70 °C, 2.10 mol% and 1:1 substrate-to-oxidant molar ratio). The efficiency was attributed to the slow tuning of the catalyst’s solubility in the reaction medium during the oxidation process by commitment of the use of an adequate solvent (acetonitrile) for efficient consumption of oxidant (TBHP) and formation of benzaldehyde. Titration experiments with TBHP, as well as an inhibitory essay, have shown the possible involvement of radical and peroxo reactive pathways in the reaction mechanism. Altogether, the results demonstrates that [Cu(L)₂]_n is suitable for accessible and mild fine chemical processes, in alignment with the search of environmentally friendly applications for industrial purposes.

在这项研究中，我们报告了基于2-乙酰基呋喃磺酰onic的新型一维铜（II）配位聚合物（[Cu（L）₂ ] _n）的合成和理化性质，以及其在液相中的催化活性。苯甲醇的氧化。基于光谱和单晶X射线衍射晶体学，Cu（II）离子是五配位的，通过N，O螯合位点键合到两个阴离子上，并与N来自第三配体分子的-吡啶基原子，其形成一维网络。评价该配位聚合物为均相催化剂，在温和的条件下（70°C，2.10 mol％和1：1的底物与氧化剂摩尔比）获得高选择性（90.1％）和对苯甲醛的收率（36.9％）。效率归因于氧化过程中催化剂在反应介质中的溶解度的缓慢调节，这是由于承诺使用适当的溶剂（乙腈）以有效消耗氧化剂（TBHP）和形成苯甲醛。用TBHP进行的滴定实验以及抑制性论文表明，自由基和过氧反应途径可能参与了反应机理。总之，结果表明[Cu（L）₂ ]_n适用于可触及的轻度精细化学过程，并与工业用途的环保应用相匹配。
