Abstract: In this study, a binuclear palladium complex immobilized on the organo-functionalized SBA-16 was prepared and structurally characterized by routine techniques. Characterizations indicated that the mesostructure of SBA-16 was maintained after the immobilization of palladium complex. Then, the prepared nanomaterial was applied as a heterogeneous catalyst in the carbonylative Suzuki coupling reaction of aryl iodides with arylboronic acids using Cr(CO)6 as carbonyl source. The catalyst was efficiently promoted the coupling reactions of various aryl iodides and arylboronic acids to give the corresponding diaryl ketones in excellent yields. Moreover, the catalyst was readily recovered by filtration and could be reused for seven cycles without losing its structural integrity and catalytic activity.

An efficient and simple palladium-catalyzed approach for the synthesis of aryl ketones from low-cost nitriles and arylhydrazines using molecular oxygen (O2) as sole oxidant via C-N bond cleavage is reported. Various aryl ketones were synthesized in moderate to good yields under mild conditions. A possible mechanism involving the PdII/Pd0 catalytic cycle process is depicted, and a cationic palladium intermediate was detected by ESI-MS.

Pd(OAc)2/di-1-adamantyl-n-butylphosphine (cataCXium A) is highly active in the three-component Suzuki carbonylation and represents the most general catalyst system reported up to now. A broad range of aryl/heteroaryl bromides and aryl boronic acids can be coupled to the corresponding diarylketones at low catalyst loadings.

Palladium-catalyzed carbonylative cross coupling reaction of organofluorosilanes with organic halides was achieved in the presence of fluoride ion and an atmospheric pressure of carbon monoxide.Alkenyl- or arylfluorosilanes effectively underwent this reaction with alkenyl or aryl iodides in moderate to good yields.Thus, highly functionalized ketones are readily available without protection of reactive functional group such as aldehyde, ketone, ester, nitril, and alcohol.For smooth ketone formation, use of organofluorosilanes is essential; tetraorganosilanes like aryl(trimethyl)silanes, upon reaction with aryl iodides, gave aroyl fluorides instead. Key Words: carbonylative coupling; organofluorosilanes; ketone synthesis
Palladium-Catalyzed Carbonylactive Coupling of Arylfluorosilanes with Aryl Iodides. A Convenient Synthesis of Diaryl Ketones

In the presence of 1 atm of carbon monoxide, arylfluorosilanes activated by potassium fluoride were found to participate in the Pd-catalyzed carbonylactive coupling reaction of aryl iodides to give unsymmetrical diaryl ketones in good yields.
