The palladium-catalyzed silylation of aryl chlorides with silylsilatranes proceeds under activator-free conditions; hence, wide functional group compatibility is displayed and boryl and siloxy groups are able to survive. Experimental and computational studies revealed that smooth transmetalation from the silylsilatrane to the arylpalladium chloride is facilitated by strong interaction between the Lewis acidic silicon and the chloride.

The alpha-arylation of sterically hindered silyl ketene acetals (SKAs) with sterically hindered aryl bromides occurs efficiently using Pd[P(t-Bu)3]2 as the optimal catalyst and ZnF2 as a promoter. Less sensitive P(t-Bu)3-based catalysts could be also employed but showed a lower activity. The reaction showed a broad scope with regard to both coupling partners, including heteroaryl bromides and cyclic SKAs. It also proved to be scalable to multigram quantities, which allowed us to further transform the ester group and to access conformationally constrained benzyl- and phenethylamines, highly sought-after building blocks for the synthesis of new agrochemicals.

We report the reductive elimination of haloarene from {Pd[P(o-tol)3](Ar)(mu-X)}2 (X = Cl, Br, I) upon addition of the strongly electron-donating, but sterically hindered, phosphine P(t-Bu)3and related ligands. Reductive elimination of aryl chlorides, bromides, and iodides from these dimeric arylpalladium(II) halide complexes was observed upon the addition of P(t-Bu)3. Conditions to observe the elimination and addition equilibria were established for all three halides, and values for these equilibrium constants were measured. Reductive elimination of aryl chlorides was most favored thermodynamically, and elimination of aryl iodide was the least favored. However, reactions of the aryl chloride complexes were the slowest. Detailed mechanistic data revealed that cleavage of the starting dimer, accompanied by ligand substitution either before or after cleavage, led to the formation of a three-coordinate arylpalladium(II) halide monomer that reductively eliminated haloarene.

We report a palladium-catalyzed method to synthesize acid chlorides by the chlorocarbonylation of aryl bromides. Mechanistic studies suggest the combination of sterically encumbered PtBu3 and CO coordination to palladium can rapidly equilibrate the oxidative addition/reductive elimination of carbon-halogen bonds. This provides a useful method to assemble highly reactive acid chlorides from stable and available reagents, and can be coupled with subsequent nucleophilic reactions to generate new classes of carbonylated products. The Good, the Bad and the Bulky! By employing a sterically encumbered phosphine ligand, tri-tert-butyl phosphine, under palladium catalysis inert aryl bromides are chlorocarbonylated to create reactive acid chlorides by reversible carbon-halogen bond reductive elimination. This general platform allows for an expanded scope of the Heck carbonylation reaction to include previously incompatible nucleophiles.
