A variety of hetero(aromatic) carboxylic acids are shown to undergo decarboxylative homocoupling, mediated by a Pd/Ag system. This novel methodology for the synthesis of symmetrical biaryls avoids the use of haloarenes and organometallic compounds as starting materials.

(Matrix presented) Palladium[0]-mediated Ullmann cross-coupling of o-halonitrobenzene (1) and various related nitroarenes with a range of α-halo-enones (e.g., 2) or -enals readily affords the expected α-arylenones, e.g., 3, or -enals, which are converted into the corresponding indoles, e.g., 4, on reaction with dihydrogen in the presence of Pd on C.

The Ullmann cross-coupling reaction of halopyridines with 2-bromonitirobenzenes was successffully catalyzed by low valent palladium [Pd(PPh3)4, PdCl2(PPh3)2, PdCl2] to afford (2-nitrophenyl)pyridine derivatives in good to excellent yield.
