Lithium perchlorate-mediated double crossed aldol condensations of a variety of aromatic aldehydes with cycloalkanones at room temperature in the presence of (trimethylsilyl)diethylamine and under solvent-free conditions are described. High to excellent yields of bis(arylmethylidene)cyclohexanones and bis(arylmethylidene)cyclopentanones are achieved within a few minutes in this facile one-pot procedure.

Keywords: Crossed aldol condensation, Bis(arylmethylidene)cycloalkanones, Lithium perchlorate, Solvent-free
