摘要: 以环境友好型H2O2作为氧化剂,探究钒基晶态材料[Ni(H2O)4][VO(PO4)]2(配合物1)对硫化物的选择性氧化催化性能。结果显示,在60 ℃下,30 min内甲基苯基硫化物的转化率高达99%,相应甲基苯基亚砜的选择性为97%。底物拓展实验显示配合物1的催化活性不受空间位阻和电子效应影响。经过五次催化循环后,配合物1仍保持结构完整性和催化活性,证实其作为可重复使用催化剂具有实用性。本文研究结果为开发高效、选择性且可重复使用的硫化物氧化催化剂提供了新思路,并在有机合成和环境治理等领域具有潜在应用价值。

Abstract: Using environmentally friendly H2O2 as the oxidant, the selective oxidative catalytic performance of the vanadium-based crystalline material [Ni(H2O)4][VO(PO4)]2 (complex 1) for sulfides was investigated. The results show that under 60 ℃, methyl phenyl sulfide achieves a conversion of up to 99% within 30 min, with a selectivity of 97% for the corresponding methyl phenyl sulfoxide. Substrate expansion experiments demonstrate that the catalytic activity of complex 1 is not significantly affected by steric hindrance or electronic effects. After five catalytic cycles, complex 1 still maintains its structural integrity and catalytic activity, confirming its practicality as a reusable catalyst. The research results of this paper provide new insights into the development of efficient, selective, and reusable sulfide oxidation catalysts, and have potential application value in fields such as organic synthesis and environmental governance.
