Abstract

A simple, improved and solvent free synthesis of a, a'-bis(arylidene)cycloalkanones

A green and efficient procedure for the synthesis of a, a'-bis(arylidene) cycloalkanones has been developed by grinding aryl aldehydes with cycloalkanones in the presence of activated barium hydroxide (C-200), in a pestle mortar with out any solvent. This is an environmentally benign protocol which not only excludes the use of organic solvents and radiations for the reaction but also gives product in good yield (84-93%) with in few minutes (3-5 min.).
