Abstract: Planar polycyclic aromatic hydrocarbons have important applications in optoelectronics, environmental chemistry and cancer researches. An improved sono-chemical synthetic procedure of dibenz[a,c]anthracene(D[a,c]A) was reported in this work. The yield was increased to 56% and the resultant was carefully characterized via gas chro- matography-electron impact mass spectrometry(GC-EIMS), matrix assisted laser desorption ionization-time of flight (MALDI-TOF), 1H NMR, 13C NMR, correlation spectrometry(1H-1H COSY), heteronuclear multiple bond correlation(HMBC) and heteronuclear multiple quantum coherence(HMQC). Based on the characterization data, we proposed a 4-step mechanistic explanation for the formation of D[a,c]A under sono-chemical bis-ortho-Wittig reaction conditions.
