2.1.4.1.3 Palladium-Catalyzed Coupling with Aryl and Hetaryl Halides

DOI: 10.1055/sos-SD-208-00147

Klapars, A.Science of Synthesis: Cross Coupling and Heck-Type Reactions, (20132228.

Palladium-catalyzed coupling of amides and aryl halides often provides complementary substrate scope to the corresponding copper-catalyzed method (Section 2.1.4.1.1). This may in part be due to differences in the reaction mechanism, a highly simplified version of which is shown in Scheme 21.[‌46‌‌48‌] The product 35 of oxidative addition of the aryl halide undergoes ligand exchange of halide X with the amide (“transmetalation”) in the presence of a base to form the complex 36. The “transmetalation” step can slow down if halide X is strongly bound to palladium, which is believed to contribute to the poor reactivity of aryl iodides with some of the palladium catalysts. It should be noted that this reactivity pattern is different from copper catalysis, in which aryl iodides are always more reactive than the corresponding aryl chlorides. The second problem in the “transmetalation” step manifests itself if the amide has poor binding affinity toward 35, as in hindered secondary amides. However, unlike copper catalysts, the palladium catalysts can be tuned to accept some of the less reactive secondary amides.[‌48‌] Finally, competitive formation of a κ2-complex 37 may also complicate palladium-catalyzed aryl amidations.[‌46‌,‌47‌]
