Summary: A novel strategy was developed for efficient production of 2-(1-hydroxyethyl)-imidazoline (HI) directly from carbohydrates under mild reaction conditions, achieving a high isolated yield. The synergistic functions of ethylenediamine (EDA) and InCl3 were identified for the transformation, promoting the scission of C-C bond of fructose backbone and facilitating the formation of reactive intermediates for HI production.

Summary: Amides, acids, and thioesters can be easily formed from precursor aryl/heteroaryl halides under micellar catalysis conditions using W(CO)(6) as a carbon monoxide source. Palladium catalysts with ligands are usually loaded at around 0.5 mol%. Higher yields were obtained with iodides compared to bromides. Applications in the pharmaceutical industry and examples from the Merck Informer Library are demonstrated. E Factor calculations and options for recycling the aqueous reaction medium are also presented.

Summary: The importance of transition metal catalysis lies in its wide range of applications, including the synthesis of chemicals, natural products, and pharmaceuticals. However, a relatively new application is the catalysis of new-to-nature reactions inside living cells. The complex environment of living cells poses challenges to transition metal catalysts due to the potential inhibition or deactivation by various biological components. In this review, we summarize the current progress in the field of transition metal catalysis, focusing on the evaluation of catalysis efficiency under living cell and biological conditions. Catalyst poisoning is a common issue in this field, and we suggest that future research should explore physical and kinetic protection strategies to enhance the reactivity of catalysts in cells.

Summary: Palladium-catalyzed hydroaminocarbonylation reactions of olefins using aliphatic amines were successfully performed under carbon monoxide atmosphere. The targeted amides were synthesized in moderate to good isolated yields without the need for acidic additives. The effect of chiral diphosphines on product distribution, including chemo-, regio-, and enantioselectivities, was also investigated.

Summary: 5-Hydroxymethylfurfural (5-HMF) is an important platform molecule derived from lignocellulosic biomass, which can be valorized into valuable compounds through catalytic transformations. The reductive amination of 5-HMF with ammonia and hydrogen offers a sustainable and straightforward approach to primary furanic amines, which have wide applications in various industries. This review highlights the metal-catalyzed reductive amination of 5-HMF, focusing on the role of metal, solid support, and reaction parameters, as well as the recyclability of catalysts and the reaction mechanism.

Summary: We demonstrate visible-light-mediated carbon-heteroatom cross-coupling reactions using a photoactive Ni(II) precatalyst. The activation of this precatalyst involves an initial intraligand charge transfer event triggered by visible light irradiation. Additionally, a porous, recyclable organic polymer for heterogeneous nickel catalysis of cross-coupling reactions is obtained through ligand polymerization.

Summary: Phenylene-bridged diphobane ligands with different substituents have been synthesized and studied in palladium-catalyzed carbonylation reactions of various alkenes. The results show different selectivities between hydroformylation and alkoxycarbonylation, with the performance also influenced by the nature and amount of acid cocatalyst.

Summary: The study demonstrates that using an imidazolium-type catalyst in melt-phase polymerization can reduce the branching in polycarbonates, especially by introducing substitutions at particular positions in the imidazolium structure. The best catalyst identified shows shorter polymerization time, lower branching levels, and lower yellowness index in the polycarbonate product.

Summary: In this study, the addition of a low-cost Janus molecule called HOS to HMS-PP successfully enhanced the expansion ratio and compressive strength of macrocellular PP foams. HOS acted as a surfactant during the extrusion foaming process, stabilizing cell growth and reinforcing the cell surface. Furthermore, HOS slightly improved the viscosity and melt strength of PP and reduced its shear viscosity as a lubricant. This approach provides a simple and economically viable materials design guideline for alleviating the trade-off between expansion ratio and compressive strength in macrocellular polymer foams.
