To explore high efficiency of the Suzuki-Miyaura reactions, an easily prepared heterogeneous palladium precatalysts bearing sterically bulky ¦Á-diimine I was covalently supported on graphene oxide (GO). The characterization of supported palladium complex was discussed in detail. A simple and efficient protocol for Pd-catalyzed cross coupling was described, which revealed that the bulky ¦Á-diimine ligand is crucial to promote the C_Ar-C_Ar 4-R¹C₆H₄R (R = Ph, thiophen-2-yl, naphthalen-1-yl, etc.; R¹ = H, Me, OMe) transformation. This immobilized system provides a straightforward access to a wide range of aryl bromides RBr with excellent functional groups tolerance.

Catalytic efficiency of palladium ion substituted in TiO₂, Ti_0.97Pd_0.03O_1.97 is successfully exploited for the oxidative homocoupling of arylboronic acid and oxidative Heck coupling reactions between arylboronic acid and olefins. The reaction protocol provides direct approach to synthesize biphenyls and cinnamates from moderate to good yield with good functional group tolerance. As a result, 11 sym. biaryls and 14 cinnamates were synthesized from readily available arylboronic acids. Ti_0.97Pd_0.03O_1.97 powder catalyst is synthesized by solution combustion method and characterized by powder X-ray diffraction. The C-C bond formation reactions were carried out by catalyst cartridge method using Ti_0.97Pd_0.03O_1.97 catalyst coated cordierite monolith. Coating of the catalyst on a cordierite monolith enhanced the applicability of the catalyst and made handling and recycling of the catalyst very easy. Catalyst was recovered and recycled for eight times in both homocoupling and oxidative Heck coupling reactions. The turnover number for both the reactions found to be 443 and 424, resp.

Ojha, Subhadra published the artcilePd-Catalyzed desulfitative arylation of olefins by N-methoxysulfonamide, Category: catalysis-chemistry, the publication is Organic & Biomolecular Chemistry (2022), 20(6), 1292-1298, database is CAplus and MEDLINE.

A novel Pd-catalyzed protocol for the desulfitative Heck-type reaction of N-methoxy aryl sulfonamides with alkenes was reported. The cross-coupling reaction was performed successfully with a variety of olefins to obtain aryl alkenes RCH=CHR¹ [R = Ph, 4-ClC₆H₄, 2-thienyl, etc.; R¹ = CN, COOH, CO₂Me, etc.]. Different substituents on the aromatic ring of N-methoxysulfonamides were also found to be compatible with the reaction conditions. Expectedly, the reaction proceeded through CuCl₂-promoted generation of the nitrogen radical and subsequent desulfonylation under thermal conditions to afford the aryl radical for the Pd-catalyzed coupling reaction. N-Methoxysulfonamide was further exploited for the synthesis of sym. biaryls in the presence of CuCl₂.

Haensch, Veit G. published the artcileSustainable and highly controlled aryl couplings revealed by systematic assessment of photoactivatable linkers, Name: 4,4′-Dimethyldiphenyl, the publication is Chemical Science (2022), 13(19), 5680-5686, database is CAplus and MEDLINE.

A metal-free, photochem. alternative (“photosplicing”) for the selective preparation of a wide range of pharmaceutically important biphenyls was reported. Whereas the traceless sulfonamide linker enabled and controls the aryl coupling, unwanted toxic byproducts were released. Therefore, it designed over 25 different temporary linkers and tested them for their suitability for the photosplicing reaction in a flow reactor. A surprisingly high number of functional groups enabled light-induced aryl fusion and identified a number of linkers for environmentally friendly procedures. A thiol-ene (click) – photosplicing sequence enabled a convenient route to biaryls such as liquid crystals.
