New synthetic route to 2, 3, 4, 5,  6-pentaphenylbenzaldehyde

Abstract

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 ^1H NMR, IR, UV-Vis and elemental analysis. Base on the analysis of the reaction intermediates, a possible mechanism of the reaction is proposed.

Key words: PHENYL GROUP, BENZALDEHYDE P, CYCLOPENTENONE P, DRY METHOD, STRUCTURAL ANALYSIS, AROMATIC ALDEHYDE
