Liu, Jianming published the artcileConstruction of the flavones and aurones through regioselective carbonylative annulation of 2-bromophenols and terminal alkynes, Synthetic Route of 4760-35-4, the publication is Tetrahedron Letters (2013), 54(14), 1802-1807, database is CAplus.
The easily available and efficient catalyst containing a benzimidazolium ligand and PdCl2(PPh3)2 demonstrated excellent catalytic activity to construct the flavones and aurones, resp. This reaction can be operated under mild conditions, affording the desired products in moderate to good yields. This protocol was used to prepare the flavones and aurones by a slight modification of amines.
