Effects of Trialkyltin and Triphenyltin Copounds on Mitochondrial Respiration

European Journal of Biochemistry, 1970
In a sucrose medium, free from anions which are effective in the anion‐hydroxide exchange catalysed by trialkyltins, the effects of these compounds on mitochondrial respiration are similar to those of oligomycin, i.e. inhibition of respiration coupled to phosphorylation, and of arsenate stimulated respiration. They do not inhibit respiration stimulated

Behavioral toxicity of trialkyltin compounds: a review.

Neurotoxicology, 1984
Triethyltin (TET) and trimethyltin (TMT) are neurotoxic organotin compounds which produce different patterns of toxicity in adult animals. Exposure to TET produces behavioral toxicity (decreased motor activity, grip strength, operant response rate and startle response amplitude) which reflects impaired neuromotor function. These deficits are consistent

Intervention by an η⁶-Organochromium Moiety Switches Chemoselectivity in Palladium-Catalyzed Reactions with Trialkyltin Compounds

Organometallics, 2001
The reaction of (chloroarene)tricarbonylchromium with hexaalkylditin under palladium catalysis does not proceed by the expected Stille reaction with addition of an SnR3 group but, instead, affords alkylarene complexes via a postulated chromium-assisted alkyl migration.

Homolytic organometallic reactions. Part 14. Homolytic reactivity of β-C–H groups in organotin compounds. An alternative source of trialkyltin radicals

J. Chem. Soc., Perkin Trans. 2, 1978
Rate constants (at –84°) for the reaction of t-butoxyl radicals with tetraethyltin at the α-methylene group to give the radical Et3SnCHCH3, and at the β-methyl group to give the radical Et3SnCH2ĊH2, are 1.2 × 104 and 4.8 × 103 l mol–1 s–1, respectively ca.

Chemischer Informationsdienst, 1978
AbstractAus Tetraethylzinn werden mit tert.‐Butoxylradikalen sowohl α‐ als auch β‐Protonen abgetrennt, wobei der 2. Prozeß langsamer abläuft als der erste und alle beide 100 bis l0O0mal schneller sind als die entsprechenden Reaktionen des Ethans.

An Investigation of the Interaction of Trialkyltin Compounds with Humic Acids

1991
As previous work has shown, the trialkyltin compounds are more toxic than their inorganic homologs [1,2] and thus, their behaviour in the environment should be investigated. Humic acids are widely distributed in soils and have diverse roles within geochemistry [3]. They combine with toxic metals and thus change the mobility and bioavailability of these

Recent studies on the mode of biological action of di- and trialkyltin compounds

1998
Organic tin compounds are characterized by the presence of at least one covalent carbon-tin bond. The compounds have a tetravalent structure and are classified as mono-, di-, tri- and tetraorganotins depending on the number of alkyl and aryl moieties. The anion is usually chloride, fluoride, oxide, hydroxide, carboxylate or thiolate.

Studies on the flavor aversions induced by trialkyltin compounds.

Neurobehavioral toxicology and teratology, 1982
These experiments were undertaken to determine the suitability of a flavor-aversion-conditioning paradigm for detecting the effects of trimethyltin and triethyltin. Both organotins produced flavor aversions whose magnitude depended jointly on the dosage administered and the number of flavor-organotin pairings.
