Iodine catalysed synthesis of 5-(arylmethylidene)rhodanines by Grinding under Solvent-Free Conditions

Abstract

5-(Arylmethylidene)rhodanines have been synthesised in 88-95% yields by Knoevenagel condensation of various aromatic aldehydes with rhodanine in the presence of a catalytic amount of iodine at room temperature by grinding under solvent-free conditions.

An Efficient Synthesis of Symmetrical Bisamides Catalysed by Molecular iodine under Neutral Conditions

“…We have previously reported several molecular iodine-catalysed organic reactions. [19][20][21] In continuation of our investigations on iodine catalysed reactions, we now report an efficient procedure for the synthesis of symmetrical bisamides from aldehydes and amides in the presence of a catalytic amount of molecular iodine under neutral conditions (Scheme 1).…”
