Additives Promote Divergent Reactivity in Photolytic Deoxygenation and Lactonization Reactions of Cobalt Alkoxycarbonyls

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
We report a carbonylation‐homolysis process to access acyl radicals that can undergo decarboxylation or cyclization onto tethered alkenes. In both cases, ligands and additives are shown to influence the outcome to give saturated or unsaturated products, in some cases with isomerization of the initial products.

Endocrine disruptors in bottled mineral water : total estrogenic burden and migration from plastic bottles [PDF]

, 2009
Background, aim, and scope Food consumption is an important route of human exposure to endocrine-disrupting chemicals. So far, this has been demonstrated by exposure modeling or analytical identification of single substances in foodstuff (e.g ...

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Toxic Effects of Tributyltin, Triphenyltin, and SnCl2 on the Development of Zebrafish (Danio rerio) Embryos

Aquaculture, Fish and Fisheries
Tin (Sn) is one of the heavy metals to which various functions in biological development are attributed in small quantities, for example, a role in cell structure, enzyme activities, and protein and carbohydrate metabolism in fish.

Selective Scrambling of Phenyl‐Stannanes: Main Group Catalysis With Aromatic Phosphorus Heterocycles

ChemistryEurope, Volume 4, Issue 4, April 2026.
Phosphinine–borane Lewis pairs catalyze the selective scrambling of phenylstannanes into SnPh4, H2, and elemental Sn. The reaction proceeds via transient SnH4 formation through reversible hydride and phenyl transfer steps within three interconnected cycles and enabled by an intrinsically weak P→B bond.

Effect of Tributyltin on the Sex Ratio in Guppy (Poecilia reticulata)

Aquatic Sciences and Engineering, 2019
In this study, the effect of tributyltin (TBT) on the sex ratio in guppy (Poecilia reticulata) during the labile period covering both embryonic and post hatching periods was investigated.

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Tributyltin: A Bottom–Up Regulator of the Crangon crangon Population?

Frontiers in Marine Science, 2019
The restrictions and the concerted action of the global ban on the use and presence of tributyltin (TBT) in marine applications to protect ecosystems in the marine environment in 2008 was mainly based on the economic impact on shellfish industries and ...

Light‐Induced Reactions of Small‐Membered Cyclic Carbonyl Compounds

European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
This review highlights recent advances in the synthesis and photochemical reactivity of cyclopropenone and cyclobutenedione. These compounds undergo photolysis upon direct excitation, and in some cases, through indirect excitation by photocatalysts. The resulting photogenerated species exhibit unique reactivity profiles that are strongly influenced by ...
