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.

Developmental toxicity of organotin compounds in animals

Frontiers in Marine Science, 2014
Organotin compounds (OTs) have been used as biocides in antifouling paints and agriculture. The IMO introduced a global ban on the use of OTs in antifouling systems in 2001 due to their high toxicity.

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.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.
