Summary: In this study, three Pd-Keggin-POMs compounds were successfully synthesized via a one-step assembly strategy, which exhibited well-defined structures and heterogeneous properties. These Pd-Keggin-POMs could efficiently catalyze the generation of benzothiadiazole, and compound 3 showed outstanding catalytic activities in Suzuki-Miyaura coupling reactions, making it one of the best catalysts reported so far. The obtained benzothiadiazoles were used as bio-probes for tracking lipid droplets in living cells, showing large Stokes shifts, low cytotoxicity, and good targeting. This research provides new insights into finding sustainable materials in life science, particularly in the development of novel bio-probe materials.

Summary: Here we present a strategy for synthesizing C-7 carboxylic acids by reacting glucose, CO2, and H2. The reaction was performed using Rh-(acac)-(CO)(2) as a catalyst and I-2 as a promoter in a binary solvent of acetic acid and water at 160 degrees C. This strategy also applies to other C(n) saccharides, yielding C(n+1) carboxylic acids with a maximum yield of 72% when glyceraldehyde was used. The reaction pathway was proposed based on several control experiments.

Summary: A new heterogeneous catalyst, TBA8[Zr(W5O18)2]middot17H2O (Zr(W5)2), was synthesized and characterized. It was found that the catalyst had a sandwich-type structure consisting of zirconium ions and mono-lacunary Lindqvist [W5O18 ]4- anions, encapsulated by TBA+ cations. This catalyst exhibited hydrophobic properties and improved catalytic efficiency by trapping reactants on its surface. Using Zr(W5)2 as a catalyst, a series of 1,5-benzodiazepines were successfully synthesized via mild and solvent-free reactions.

Summary: Four novel ionic liquid compounds supported on boehmite were synthesized and used with AlCl3 to polymerize Raffinate 1 to polybutene for viscosity improver applications. The supported ionic liquids were characterized using various analytical techniques. The introduction of the supported ionic liquids resulted in polybutenes with comparable Mn and D values to the blank AlCl3 system but with lower exo-olefins content, making the copolymer more suitable for the target application. The suggested AlCl3/ionic liquid initiating system enables greener polymerization by reducing the dosage of hazardous AlCl3 compared to the blank system.

Summary: In this study, three Keggin-type heteropolyacids were impregnated on halloysite to produce heterogeneous acidic catalysts for synthesizing 5-HMF. The role of halloysite in the catalyst's acidic properties and performance was found to be important. The reaction parameters for the optimal catalyst were adjusted using Response Surface Methodology, resulting in a 99.5% yield of the target compound after 43 minutes at 125 degrees C in DMSO solvent. Immobilization of silicotungstic acid on halloysite significantly reduced leaching-out, with only a 12.5% loss of activity in five consecutive reaction cycles. The catalyst's activity was also tested on converting different carbohydrates to 5-HMF, with glucose showing the highest product yield of 64.24%. Furthermore, the kinetic and thermodynamic parameters of the conversion of fructose to 5-HMF were determined.
