A Convenient Palladium Catalyzed Synthesis of Symmetric Biaryls, Biheterocyand Biaryl Chiral Diamides. — Direct homocoupling of iodoarylbenzamides
34- 119 cles
occurs in the presence of a palladium catalyst system, Et3N as base and MeCN as solvent. No cross product is formed under these conditions if two different iodoarylbenzamides are present. The method works also well for chiral amides (III) and pyridines (V) and (VII) [no yields given for products (VI) and (VIII)]. — (GOSWAMI*,
