, p. 581 - 583 (2004)
A simple and efficient method for synthesis of asymmetric branched functionalized triarylbenzenes is presented. The dypnone reacting with different substituted acetophenones, corresponding asymmetric 1,3,5-triarylbenzenes were obtained in the presence of catalytic amounts of sulfurous oxychloride in anhydrous ethanol.
N-Heterocyclic Carbene-Catalyzed Construction of 1,3,5-Trisubstituted Benzenes from Bromoenals and α-Cyano-β-methylenones

, p. 6408 - 6411 (2016)
A direct and efficient approach to 1,3,5-trisubstituted benzenes has been developed via N-heterocyclic carbene-catalyzed [2 + 4] annulation of α-bromoenals and α-cyano-β-methylenones. The reaction worked well for both aryl- and alkylenones.
