, p. 1199 - 1207 (2015)
Very small concentrations of a dimeric C,N-palladacycle were used as an efficient homogeneous catalyst for Sonogashira cross-coupling reactions between various aryl halides and phenylacetylene. The catalytic reactions were performed without the need for copper in DMF/H2O. This catalytic system shows excellent yields for aryl iodides and bromides and even in the case of aryl chlorides.

Kim, Hee Jae,Choi, Jinseop,Choe, Jaehoon,Song, Kwang Ho,Lee, Sunwoo
, p. 37181 - 37184 (2017)
A continuous flow reaction system in which a palladium magnetic catalyst was immobilized and vibrated by an alternating induced magnetic field was developed. The alternating electromagnetic field improved the mixing efficiency and catalytic activity for the palladium-catalyzed coupling reactions. This flow reaction system showed good product yields for various reactions such as Sonogashira, Heck, Suzuki, Stille, Hiyama and decarboxylative coupling reactions.
