Title
Silicate intercalated cobalt chromium–hydrotalcite (CoCr–HTSi): An environment-friendly recyclable catalyst for organic transformations
Abstract

•Silicate intercalated CoCr–HT first time prepared by sol–gel method•Retention of layered structure was evident from XRD.•The developed materials showed remarkable activity for allylic and alcohol oxidation.•No leaching was evident and the catalyst is recyclable.

Silicate intercalated cobalt chromium hydrotalcite (CoCr–HTSi) was prepared for the first time by a simple sol–gel method. The resultant CoCr–HTSi yielded remarkable activity for allylic oxidation of cyclohexene and aromatic alcohols in the presence of environmentally-friendly conditions, viz., H2O2 as oxidant and methanol as oxidant. More importantly, the active species remain intact on the surface and no leaching occurred under the reaction conditions. The catalysts are recyclable even after four cycles, and have shown to be as truly heterogeneous in nature.

Graphical abstractCoCr–HTSi materials were prepared and shown as promising catalysts for oxidation of cyclohexene and alcohols using H2O2 as oxidant in eco-friendly conditions. The material is found to be free from leaching of active species found to be truly heterogeneous in nature.Figure optionsDownload full-size imageDownload as PowerPoint slide
