Abstract
Immobilized Pd-catalyzed Suzuki-Miyaura coupling under continuous-flow conditions using a packed-bed reactor, representing an efficient, automated, practical, and safe technology compared to conventional batch-type reactions. The core objective of this study is the development of an active and durable catalyst. In contrast to supported Pd nanoparticles, the attachment of Pd complexes onto solid supports through well-defined coordination sites is considered a favorable approach for preparing highly dispersed and stabilized Pd species. These species can be directly employed in various flow reactions without the need for pre-treatment. This concept paper explores recent achievements involving the application of immobilized Pd complexes as precatalysts for continuous-flow Suzuki-Miyaura coupling. Our focus is to elucidate the significance of the designed catalyst structures in relation to their catalytic performance under flow conditions. Additionally, we highlight various reaction systems and catalyst packing methods, emphasizing their crucial roles in establishing a practical synthesis process.

Abstract
My mission in catalysis research is to develop highly active and reusable supported catalytic systems in terms of fundamental chemistry and industrial application. For this purpose, I developed three types of highly active and reusable supported catalytic systems. The first type involves polymeric base-supported metal catalysts: Novel polymeric imidazole-Pd and Cu complexes were developed that worked at the mol ppm level for a variety of organic transformations. The second involves catalytic membrane-installed microflow reactors: Membranous polymeric palladium and copper complex/nanoparticle catalysts were installed at the center of a microtube to produce novel catalytic membrane-immobilized flow microreactor devices. These catalytic devices mediated a variety of organic transformations to afford the corresponding products in high yield within 1-38 s. The third is a silicon nanowire array-immobilized palladium nanoparticle catalyst. This device promoted a variety of organic transformations as a heterogeneous catalyst. The Mizoroki-Heck reaction proceeded with 280 mol ppb (0.000028 mol%) of the catalyst, affording the corresponding products in high yield.

Abstract
This review describes our recent efforts in the development and application of new oxidation systems utilizing oxometalate catalysts. The novel use of heteropoly acid (HPA), an acidic oxometalate catalyst, in hypervalent iodine-mediated oxidations provided an effective strategy to generate cation radical species that enables a variety of direct C-H functionalizations of aromatic compounds. This strategy brought a facile biaryl synthesis and new spirodienone syntheses in aromatic oxidation chemistry. Moreover, this strategy opens up a facile synthetic route to morphinandienone alkaloids. On the other hand, the use of oxometalate catalyst together with poly(N-isopropylacrylamide) (PNIPAAm)-based polymer in the development of new solid-phase catalyst provided a novel reaction system in water. Due to the characteristic temperature-responsive intelligence of PNIPAAm, this reaction system brought a remarkable acceleration of the reactivity and ease of catalyst recovering in catalytic oxidation that uses hydrogen peroxide or oxygen gas (O<inf>2</inf>) as primary oxidant. In addition, the recovered solid-phase catalyst could be used for consecutive reactions without any significant loss of its catalytic efficacy.

Abstract
We have developed a variety of polymeric palladium-nanoparticle membrane-installed microflow devices. Three types of polymers were convoluted with palladium salts under laminar flow conditions in a microflow reactor to form polymeric palladium membranes at the laminar flow interface. These membranes were reduced with aqueous sodium formate or heat to create microflow devices that contain polymeric palladium-nanoparticle membranes. These microflow devices achieved instantaneous hydrodehalogenation of aryl chlorides, bromides, iodides, and triflates by 10-1000 ppm within a residence time of 2-8 s at 50-90 °C by using safe, nonexplosive, aqueous sodium formate to quantitatively afford the corresponding hydrodehalogenated products. Polychlorinated biphenyl (10-1000 ppm) and polybrominated biphenyl (1000 ppm) were completely decomposed under similar conditions, yielding biphenyl as a fungicidal compound.

Abstract
The design, synthesis and solid state structures of a new class of xylylene-linked bis(1,4- piperazine-2,5-diones) are reported in an effort to extend the molecular framework of piperazine-2,5-diones. These compounds were derived from piperazine-2,5-dione as the core structure, synthesized via a new efficient route, and their crystal structures were determined. We examined the effects of side chain substitution on conformations of the linked bis-DKPs. Crystallization of 3,3'-[1,4-phenylenebis(methylene)]-bis[6-(hydroxymethyl)-1,4-dimethylpiperazine-2,5-dione] yielded molecular solids with an unusual network of "C"-shaped monomers held together by four intermolecular hydrogen bonds per asymmetric unit. Similarly, intermolecular interactions between the iodomethyl groups in 3,3'-[1,4-phenylenebis(methylene)]-bis[6-(iodomethyl)-1,4-dimethyl-piperazine-2,5-dione] result in the monomers adopting a "C"-shape in the solid state. Assembly of the monomers with side chains converted to methyl groups or tert-butyldimethylsilyl ethers, thereby lacking these stabilizing intermolecular interactions, results in an infinite array of "S"-shaped conformations. These results suggest that the interplay between the attractive intermolecular interactions and repulsive steric interactions of the substituents at the C6 and C6' positions of the diketopiperazine rings is important in determining the solid-state conformations of xylylene-linked bis(piperazine-2,5-diones).

Abstract
[reaction: see text] A tightly convoluted polymeric phosphotungstate catalyst was prepared via ionic assembly of H3PW12O40 and poly(alkylpyridinium). An oxidative cyclization of various alkenols and alkenoic acids was efficiently promoted by the polymeric catalyst in aq H2O2 in the absence of organic solvents to afford the corresponding cyclic ethers and lactones in high yield. The catalyst was reused four times without loss of catalytic activity.

Abstract
[reaction: see text] A novel solid-phase self-organized catalyst of palladium nanoparticles was prepared from PdCl(2) with main-chain viologen polymers via complexation and reduction. This insoluble nanocatalyst nano-Pd-V efficiently promoted alpha-alkylation of ketones with primary alcohols in the presence of Ba(OH)(2).H(2)O under atmospheric conditions without organic solvents. The nano-Pd-V catalyst was reused without loss of catalytic activity.
