2,3,4,5,6 - Pentaphenylbenzaldehyde was synthesized via the direct addition of tetraphenylcyclopenta - 2,4 - dien - 1 - one to ethylene glycol acetal of cinnamaldehyde with elimination of CO at 260 - 270℃ , followed by oxidation and hydrolysis. The structure of the target molecule was characterized by H NMR, IR, UV - Vis and elemental analysis. Base on the analysis of the reaction intermediates, a possible mechanism of the reaction is proposed.

This study presents a new synthetic route to 2,3,4,5,6-pentaphenylbenzaldehyde by directly adding tetraphenylcyclopenta-2,4-dien-1-one to ethylene glycol acetal of cinnamaldehyde, followed
