“…The catalytic performance of xNb/SBA-15(y) materials was subsequently explored in propanoic acid esterification with methanol at 60 °C. These experimental conditions were chosen based on previous optimized studies for solid acid catalysed esterification reactions [64,65], with a high methanol content chosen to both drive the reaction equilibrium and act as a solvent to ensure good mass transport. The parent SBA-15 was inactive under these conditions, confirming the requirement for solid acidity.…”

Highlights  Niobium-containing SBA-15 silica used as catalysts for a model reaction to biodiesel production.  High niobium content and high calcination temperature maintained SBA-15 mesoporous silica profile.  Solid evaluated as catalyst with low Nb concentration (2 wt.%) showed better catalytic performance.  Nb promoter effect: catalyst stability at low loadings and also lowest heating treatment.

“…Lately, Kim et al described the first demonstration of an oxidative coupling reaction between numerous dialkyl/dibenzyl ethers and ortho -acyl phenols to form phenol esters using Cu(OAc) 2 as a catalyst . To add to the green features for the transformation, solid catalysts should be explored. , Moreover, the contamination of phenol esters with hazardous metals would be reduced if it is possible to reuse the solid catalyst. − …”

A metal−organic framework (MOF) Cu 2 (dhtp) was prepared and used as a recyclable catalyst for the direct C−O coupling of ethers with 2-acylphenols to generate phenol esters. The Cu 2 (dhtp) displayed better efficiency in the production of phenol esters than several MOFs, as well as traditional homogeneous catalysts. The oxidant played an important role for the conversion, and aqueous tert-butyl hydroperoxide was the best choice. Heterogeneous catalysis was confirmed for the transformation, and no phenol ester generated by leached species, if any, was recorded. It was possible to reuse the Cu 2 (dhtp) catalyst numerous times in the conversion of 2-acylphenols and ethers to phenol esters without a noticeable deterioration in catalytic efficiency. To our best understanding, the direct esterification to produce phenol esters utilizing ethers as an acylating source assisted by solid catalysts has not been previously reported in the literature.
