A palladium-catalyzed carbonylative addition reaction of aryl bromides, amines, and alkynes has been developed. The reaction occurs readily in N,N-dimethylformamide with PdCl2(PPh3)2 as a catalyst to give the corresponding enaminones in medium to excellent yields. Furthermore, a mechanism for the palladium-catalyzed four-component carbonylative addition reaction is proposed.
已开发出钯催化的芳基溴化物、胺和炔烃的羰基化加成反应。该反应在 N,N-二甲基甲酰胺中以 PdCl2(PPh3)2 作为催化剂很容易发生,以中等至极好的收率得到相应的烯胺酮。此外,提出了钯催化的四组分羰基化加成反应的机理。
