Environmentally Desirable Synthesis: One-pot And Solvent ‎free Formation Of Arylidenes Compounds From Gem-diacetates



Authors : Benferrah N . Hammadi M . Dokari H . Berthiol(‎ F .

Abstract

Heterogeneous acid catalysts are of importance in the fine ‎chemicals area, and several been investigated in reactions such as ‎the Knoevenagel reaction, an important reaction with pronounced ‎solvent dependency. The condensation of active methylene ‎compounds with gem-diacetates in the presence of acid ‎aluminosilicates (montmorillonite KSF, K10/ZnCl2) without solvent ‎and under microwave irradiation, an efficient of synthesis of ‎arylidenes compounds without isolation of aldehydes compounds. ‎Cleavage of arylidene rhodanine derivative in position 5 in basic ‎medium on Potassium Fluoride–Barium Oxide (BaO-KF) under ‎focused microwave irradiation and free solvent is a simple and ‎effective method for synthesis of, β-aryl-α-thiolacrylic acids.‎
