Abstract

Bromoflavones were treated with various terminal alkynes in palladium-catalyzed cross-coupling reactions under phosphine-free condions to give the expected alkenylated flavones in moderate to good yields. The presence of two different β hydrogens in the terminal alkene led to the formation of both alkenylated and alkylated products.
