• Trityl chloride (Ph3CCl)
• Trityl carbocation
• Organocatalyst
• Cross-aldol condensation
• alpha,alpha '-Bis(arylidene)cycloalkanone
• Solvent-free

Organocatalyst trityl chloride (Ph3CCl), by in situ formation of trityl carbocation with inherent instability, efficiently promotes the cross-aldol condensation reaction between cycloalkanones and arylaldehydes in solvent-free and homogeneous media to afford alpha,alpha'-bis(arylidene)cycloalkanones in high yields. Moreover, an attractive and plausible mechanism based on observations and the literature is proposed for the reaction.
