synthesis of phenoxathiinderivatives. A range of 1,2-dihaloarenes or 1-halo-2-nitroarenes reacted with 2-sulfanylphenol to give the desired products in good-to-excellent yields. It is intriguing that 1-halo-2-nitroarenes containing electron-donating groups worked well as substrates in this reaction. A simple and efficient method was developed for the synthesis of phenoxathiinderivatives. A range of

copper supported on manganese oxide-based octahedral molecular sieves OMS-2 (CuOx/OMS-2), the heterogeneously catalytic synthesis of phenoxathiinan derivatives via intramolecular arylations of phenols with aryl bromide or aryl chloride has been achieved. TEM and XRD have confirmed the CuOx/OMS-2 catalyst has been successfully reused 8 times without a significant decrease in the yield, with simple filtration
苯氧ath啶及其衍生物因其独特的化学和物理性质及其在荧光材料,抗真菌活性和选择性抑制剂中的应用而引起了人们的极大兴趣。在以氧化锰为基础的八面体分子筛OMS-2(CuO x / OMS-2)上负载铜的情况下,已实现了苯酚分子间芳基化反应通过苯酚与芳基溴化物或芳基氯化物进行苯并噻吩南衍生物的非均相催化合成。TEM和XRD证实,CuO x / OMS-2催化剂已成功重复使用了8次,而收率没有显着下降,并且通过简单的过滤和洗涤作为分离手段。

The ligand-free and simple cascade C-H hydroxylation-C-S coupling-C-O cyclization reaction has been used as the synthetic approach to disulfides and o-chloro-iodobenzenes using CuI as a catalyst. This approach provides an easy and convenient method of synthesis of phenoxathiin derivatives.
