Seo, Tamae;Ishiyama, Tatsuo;Kubota, Koji;Ito, Hajime research published 《 Solid-state Suzuki-Miyaura cross-coupling reactions: olefin-accelerated C-C coupling using mechanochemistry》, the research content is summarized as follows. The first broadly applicable mechanochem. protocol for a solid-state palladium-catalyzed cross-coupling reaction of arylhalides ArX (Ar = benzothiophen-5-yl, anthracen-9-yl, biphenyl-4-yl, etc.; X = Cl, Br, I) and boronic acids RB(OH)₂ (R = 4-methoxyphenyl, 1-naphthyl, thiophen-3-yl, etc.) using an olefin additive has been reported. Compared to previous studies, the newly developed protocol shows a substantially broadened substrate scope. This mechanistic data suggest that olefin additives might act as dispersants for the palladium-based catalyst to suppress higher aggregation of the nanoparticles, and also as stabilizer for the active monomeric Pd(0) species, thus facilitating these challenging solid-state C-C bond forming cross-coupling reactions.

Sato, Takeo;Shimada, Shigeru;Hata, Kazuo research published 《 Photo-aryl coupling and related reactions. II. Formation of triphenylenes from halo-o-terphenyls》, the research content is summarized as follows. Electronic effects on the photochem. conversion of o-terphenyl to triphenylene were examined by comparing the uv irradiation reaction, carried out in benzene using iodine as an oxidant, of three classes of o-terphenyl derivatives, 4- (I) and 4′-substituted (II) and 4,4”-disubstituted derivatives (III). While a strong electron-withdrawing group such as nitro group, hindered the cyclization reaction to occur, methoxy, fluoro, chloro and bromo compounds afforded the corresponding triphenylene derivatives With bromo and iodo compounds, however, a complex mixture of the products resulted due to photochem. cleavage of a carbon-halogen bonding, which led to the formation of phenylation products and hence phenyltriphenylenes together with reduction products. Further, with iodo compounds, it was found that no oxidant was necessary to effect the cyclodehydrogenation reaction since iodine was liberated during the photolysis. Possible pathways for the formation of the photolysis products from bromo and iodo compounds were discussed in relation to the relative rates of carbon-halogen cleavage and cyclization reactions. Comparison among three classes of halo compounds indicated that, with the exception of iodides, the cyclization reaction occurred more readily with type II compounds than type I compounds, while type III compounds reacted only with difficulty.

Rawat, Vishal Kumar;Higashida, Kosuke;Sawamura, Masaya research published 《 Nickel-Catalyzed Homocoupling of Aryl Ethers with Magnesium Anthracene Reductant》, the research content is summarized as follows. Nickel-catalyzed reductive homocoupling of aryl ethers has been achieved with Mg(anthracene)(thf)₃ as a readily available low-cost reductant. DFT calculations provided a rationale for the specific efficiency of the diorganomagnesium-type two-electron reducing agent. The calculations show that the dianionic anthracene-9,10-diyl ligand reduces the two aryl ether substrates, resulting in the homocoupling reaction through supply of electrons to the Ni-Mg bimetallic system to form organomagnesium nickel(0)-ate complexes, which cause two sequential C-O bond cleavage reactions. The calculations also showed cooperative actions of Lewis acidic magnesium atoms and electron-rich nickel atoms in the C-O cleavage reactions.

Kyushin, Soichiro;Fujii, Hidetoshi;Negishi, Keisuke;Matsumoto, Hideyuki research published 《 Improvement of the fluorescence quantum yield of triphenylene by the rotational effect of 4-(trimethylsilyl)phenyl groups》, the research content is summarized as follows. The fluorescence quantum yield of triphenylene is low because the transition moment between the HOMOs and the LUMOs is negligibly small. To improve the fluorescence quantum yield, break of the sym. structure of triphenylene is necessary. We found that the rotational effect of the 4-(trimethylsilyl)phenyl groups of 2,3,6,7,10,11-hexakis[4-(trimethylsilyl)phenyl]triphenylene is effective to break the symmetry in spite of the sym. structure, leading to improvement of the fluorescence quantum yield.

The palladium-catalyzed solid-state C-N cross-coupling of carbazoles with aryl halides via a high-temperature ball-milling technique was reported. This reaction allowed simple, fast, and efficient synthesis of N-arylcarbazole derivatives I [R¹ = 4-MePh, 2-naphthyl, 9-pyrenyl, etc.; R² = H, t-Bu, Ph, etc.] in good to excellent yields without the use of large amounts of organic solvents in air. Importantly, the developed solid-state coupling approach enabled the cross-coupling of poorly soluble aryl halides with large polyaromatic structures that are barely reactive under conventional solution-based conditions.

Kubota, Koji;Kondo, Keisuke;Seo, Tamae;Ito, Hajime research published 《 Insight into the Reactivity Profile of Solid-State Aryl Bromides in Suzuki-Miyaura Cross-Coupling Reactions Using Ball Milling》, the research content is summarized as follows. Despite recent advances in solid-state organic synthesis using ball milling, insight into the unique reactivity of solid-state substrates, which is often different from that in solution, has been poorly explored. In this study, author’s investigated the relationship between the reactivity and m.ps. of aryl halides in solid-state Suzuki-Miyaura cross-coupling reactions and the effect of reaction temperature on these processes. Author’s found that aryl halides with high m.ps. showed significantly low reactivity in the solid-state cross-coupling near room temperature, but the reactions were notably accelerated by increasing the reaction temperature Given that the reaction temperature is much lower than the m.ps. of these substrates, the acceleration effect is most likely ascribed to the weakening of the intermol. interactions between the substrate mols. in the solid state. The present study provides important perspectives for the rational design of efficient solid-state organic transformations using ball milling.
