Homoisoflavonoids were formed in DMSO exclusively, and flavones were formed in t-AmOH when salicylaldehyde and alkynoicacids reacted with [Ru(p-cymene)Cl2]2 and CsOAc. They were formed through C–H activation of salicylaldehyde and decarboxylative coupling of alkynoicacid. This reaction system showed good yields, broad substrate scope, and good functional group tolerance. It was found that chalcone
