Organotin salts, used as antilouling substances have a deleterious effect on the environment. particularly on molluscs and especially on the Japanese oyster Crassostrea gigas. A synthesis 01 the effects 01 tributyltin (TBT) on cultured molluscs reveals the lollowing effects: 1) acute and chronic loxicity to the adults; 2) accumulation in the f1esh 01 the adults; 3) perturbation 01 reproduction ...

The preparation of polymer-supported allyltin reagents was shown to be possible for both unfunctionalized and functionalized allyl units. These reagents were treated with aldehydes in the presence of cerium(III) or indium(III) salts to afford high yields of homoallylic alcohols, practically uncontaminated with organotin residues (less than 5 ppm). Some mechanism aspects are briefly discussed an...

An intramolecularly P=O-coordinated dicationic diorganotin sulphide is presented. In solution, it shows a monomer-dimer equilibrium.

Samples of blue mussel (Mytilus trossulus) and sediment were collected in the Gulf of Gdańsk (Southern Baltic Sea) to assess the extent of their contamination with two groups of endocrine disruptors: 4-nonylphenols and organotins (butyl- and phenyltins). Five sampling stations were chosen along the coastline of the Tricity Agglomeration (Gdańsk, Sopot, Gdynia) in 2008, 2012, and 2013. No eviden...

The asymmetric unit of the title cocrystal, [Sn(CH(3))(C(6)H(5))Cl(2)(H(2)O)(2)]·C(10)H(20)O(5), contains two independent for-mula units. The organotin molecules exhibit a six-coordinate metal atom and are linked to the crown ether molecules by water-crown ether O-H⋯O hydrogen bonds into a linear chain running along [101]. Each coordinated water mol-ecule forms a pair of hydrogen bonds to the s...

Tributyltin (TBT) is one of the most toxic anthropogenic compounds introduced into the marine environment. Despite its global ban in 2008, TBT is still a problem of great concern due to its high affinity for particulate matter, providing a direct and potentially persistent route of entry into benthic sediments. Bioremediation strategies may constitute an alternative approach to conventional phy...

The syntheses of tris(organostannyl)methanes HC(SnX n Ph(3-n))3 (1, n=0; 2, n=1, X=I; 3, n=1, X =F; 4, n=1, X=Cl; 5, n=1, X=OAc; 6, n=2, X=I; 7, n=2, X=Cl) and the organostannate complexes Et4N[HC(SnIPh2)3⋅F] (8), Ph4P[HC(SnClPh2)3⋅Cl] (9), and [Ph4P]2[HC(SnCl2Ph)3⋅2 Cl] (10) are reported. The compounds were characterized by 1H, 13C, 19F, and 119Sn NMR spectroscopy, IR spectroscopy, electrospra...

Organotin (IV) carboxylates with the general formulae R2Sn(Cl)L [R = Me (1), n-Bu (2), Ph (3)] and R3SnL [R = Me (4), Ph (5)] have been synthesized by the reaction of 4-piperidinecarboxylic acid (HL) with KOH and R2SnCl2 (R = Me, n-Bu, Ph)/R3SnCl (R = Me, Ph) in methanol under stirring conditions. The metal ligand binding site, structure, and stability of complexes have been verified by FT-IR, ...

The organotin monomer di(tri-n-butyltin) citraconate (DTBTC, I) was synthesized. Subsequently this monomer was copolymerized with N-vinylimidazole (VI) using a free radical technique. The overall conversion was kept low (< or = 14% wt/wt) for all studied samples and the copolymer composition was determined from tin analysis using the Gilman and Rosenberg method. The synthesized monomer and copo...
