Abstract:

A green and efficient method for synthesis of α,α'  -bis (arylidene) cycloalkanones, starting from aromatic aldehydes in reaction with ketones using sulfonated polyethylene glycol 6000 (PEG-SO3H) as a stable, reusable and biodegradable catalyst under solvent-free conditions at 80 °C is described. The use of a nontoxic, inexpensive, easily available and recyclable catalyst makes this protocol practical, environmentally friendly and economically attractive.

Keywords: α, α'-bis(arylidene) cycloalkanones, Crossed-aldol condensation, PEG-SO3H, Solvent-free conditions
