title: Crossed-aldol condensation of cycloalkanones with aromatic aldehydes catalyzed by copper(II) trifluoroacetate.
abstract: A simple and solvent-free procedure to synthesize alpha,alpha'-bis(substituted benzylidene) cycloalkanones, catalyzed by copper(II) trifluoroacetate through crossed-aldol condensation of various aromatic aldehydes with cyclic ketones is reported. The reaction proceeded smoothly in good to excellent yields.
