(a) Interpretation: The missing reactant that is necessary to carry out the given transformation is to be drawn. Concept introduction: The palladium catalysed reactions are namely Suzuki coupling and Heck coupling which form a new C-C bond. In Suzuki coupling reaction, a vinylic or aryl halide R-X is treated with an organometallic compound R’-B ( OR” ) 2 and a palladium catalyst ( PdLn ) under basic conditions. Suzuki reaction is stereospecific involving possible E/Z isomerism usually with retention of configuration. Similar to the Suzuki reaction, the Heck reaction can couple one vinylic or aryl group to another. If R-X halide in a Heck reaction is vinylic, the configuration about the double bond is retained. If H-R’ is vinylic and has an attached substituent at the opposite end of the C=C , then R and the substituent will be trans to each other in the product.
