The Modified Clay as a New and Eco-Friendly Catalyst for the Knoevenagel Reaction
Abstract This work aims the synthesis of substituted alkenes via Knoevenagel condensation using the clay collected from the Agadir region and modified by KF as a heterogeneous catalyst (KF-modified clay). In this context, the influence of various parameters on the reaction yield was studied, and the...

The Modified Clay as a New and Eco-Friendly Catalyst for the Knoevenagel Reaction |
| abstract |
Abstract This work aims the synthesis of substituted alkenes via Knoevenagel condensation using the clay collected from the Agadir region and modified by KF as a heterogeneous catalyst (KF-modified clay). In this context, the influence of various parameters on the reaction yield was studied, and the reuse of catalyst was carried out. The results obtained show that KF-modified clay is very effective for the preparation of substituted alkenes giving excellent yields (87–99%) and in very short times (between 2–4 s and 8 min) under mild and heterogeneous conditions. In addition, the recycling of our catalyst indicates that our material can be reused several times without losing its catalytic activity. © Pleiades Publishing, Ltd. 2020 |

Abstract This work aims the synthesis of substituted alkenes via Knoevenagel condensation using the clay collected from the Agadir region and modified by KF as a heterogeneous catalyst (KF-modified clay). In this context, the influence of various parameters on the reaction yield was studied, and the reuse of catalyst was carried out. The results obtained show that KF-modified clay is very effective for the preparation of substituted alkenes giving excellent yields (87–99%) and in very short times (between 2–4 s and 8 min) under mild and heterogeneous conditions. In addition, the recycling of our catalyst indicates that our material can be reused several times without losing its catalytic activity. © Pleiades Publishing, Ltd. 2020 |
