Main Group Metals in Redox Catalysis

European Journal of Inorganic Chemistry, Volume 29, Issue 22, 1 August 2026.
Main group metal redox catalysis is emerging as a credible alternative to transition metal chemistry. Elements from groups 13 to 15 now enable diverse catalytic manifolds, driven by ligand design and control of electronic structure. This review highlights recent advances, key design principles, and remaining challenges, positioning main group metals as

Organotin-drug interactions. Organotin adducts of tenoxicam: Synthesis and characterization of the first organotin complex of tenoxicam

, 2000
The synthesis and spectral characterization of the novel organotin complexes [SnBu2(ten)] (1) and [SnBu2(Hten)(2)] (2) or the potent and widely used anti-inflammatory drug tenoxicam (H(2)ten) are reported. A crystal-structure determination of 1 showed that, in this complex, the ligand is doubly deprotonated at the hydroxy O-atom and the amide N atom ...

Monitoring the Effect of Tributyltin Salicylate and Propionate, Retinoid X Receptor Ligands, on Heat Shock Protein Expression in MDA‐MB‐231 Cells by MALDI MS/MS

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Organotin (IV) compounds are known to induce apoptosis via the intrinsic mitochondrial pathway, which is a key mechanism of effective anticancer therapy. Their ability to selectively promote apoptotic cell death highlights their potential as chemotherapeutic agents. In this study, the in vitro effects of two triorganotin compounds, tributyltin

Enhanced Dehydrogenation and Hydrogenation Capacity of Poly(5‐Vinyl‐1‐Indanol) at Low Temperatures

Polymers for Advanced Technologies, Volume 37, Issue 7, July 2026.
ABSTRACT Redox‐active polymer‐based hydrogen carriers store hydrogen gas through chemical bonding. Although existing redox‐active polymers utilized as hydrogen storage units (e.g., fluorenone and fluorenol) demonstrate reversible hydrogenation in the presence of iridium complex catalysts, they are often hindered by low weight‐based hydrogen storage ...

Organotin pollution at Arraial do Cabo, Rio de Janeiro State, Brazil: increasing levels after the TBT ban

Brazilian Journal of Oceanography, 2011
Imposex, an endocrine disruption phenomenon, is a biomarker of tributyltin (TBT) exposure in marine gastropod populations. The occurrence and intensity of the syndrome in populations of the neogastropod Stramonita haemastoma were ascertained at nine ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, Volume 32, Issue 4, Page 1049-1077, July 2026.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Phosphoryl Halogen and Hydrogen Bonding Controls the Solid‐State Structures of Aryl Halide‐Containing Phosphonates

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Intramolecular (RO)2PO→Halogen interaction versus intermolecular (RO)2PO···HOH hydrogen bonds. Although the O···I distance is shorter than the sum of the van der Waals radii of the atoms involved, there is no covalency involved in this interaction.

Durable Biofouling‐Resistant Coated Fabric Based on Aerogel/Polyurethane for Marine Applications

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
A multilayer composite protective fabric (PUC‐CME/KF) is developed by integrating carboxymethyl chitosan/coral extract aerogel and capsaicin‐loaded polyurethane onto a knitted substrate. The material exhibits exceptional extensibility (1963% elongation at break) and sustained capsaicin release.
