Usage

Uses

Used in Plastics Industry:
Ethyltriphenyltin is used as a stabilizer in the production of polyvinyl chloride (PVC) plastics for its ability to prevent the degradation of PVC polymers caused by heat and light exposure. This function is crucial in maintaining the integrity and longevity of PVC products.
However, due to its classification as a hazardous substance and the acute toxic effects it can have on aquatic life, the use of ethyltriphenyltin has been regulated in some regions. This has led to a decrease in its application in PVC production, with the industry shifting towards more environmentally friendly stabilizers to mitigate the harmful environmental impact.

Synthesis, characterization, and molecular structures of di- and triorganotin(IV) complexes with 9-anthracenecarboxylic acid: The structural diversity in organotin 9-anthracenecarboxylates

The di- and triorganotin(IV) derivatives of anthracenecarboxylic acid, Ph2MeSnOC(O)C14H9 (2), Me3SnOC(O)C14H9 (3), Me2Sn[OC(O)C14H9]2 · CH3OH (4) Ph3SnOC(O)C14H9 · CH3OH (5), Ph2EtSnOC(O)C14H9 (6), Ph2Sn[OC(O)(C14H9)]2 (7) and PhMe2SnOC(O)C14H9 (8) were synthesized by the reaction of Ph2MeSnI, Me3SnCl, Me2SnCl2, Ph3SnCl, Ph2EtSnI, Ph2SnCl2, and PhMe2SnI with 9-anthracenecarboxylic acid, respectively, with the aid of potassium iso-propoxide. All complexes were characterized by elemental analysis, mass spectrometry, IR, 1H, 13C and 119Sn NMR spectroscopes. The molecular structures of complexes 2, 3 and 4 were determined by single crystal X-ray analysis. The X-ray structures reveal that complex 2 and 3 adopt a polymeric trans-C3SnO2 trigonal bipyamidal configuration with the oxygen atoms occupying axial positions. Complex 4 adopts a monomeric structure with two carboxylates coordinated to tin in a monodentate form from axial and equatorial positions, and with the coordination number raised to five as the methanol occupies the apical position of the trigonal bipyramid.

Synthesis, structural characterization and antimicrobial activity of mixed aryl-alkyl diorganotin(IV) compounds with quinoline-2-carboxylate (L -): {RR'SnLCl}n and RR'SnL2

A series of unsymmetrical diorganotin derivatives of quinoline-2-carboxylic acid (LH), namely polymeric {MePhSnClL}n (1) and {EtPhSnClL} n (2), and mononuclear MePhSnL2 (3) and EtPhSnL 2 (4), was synthesized by the reaction of LH with the MePhSnCl 2, EtPhSnCl2, MePhSnO, and EtPhSnO precursors, respectively. The compounds were characterized by elemental analysis and infrared spectroscopy, as well as by 1 H, 13 C and 119Sn NMR. The molecular structures of representative compounds 2 and 4 were determined by single-crystal X-ray crystallography. This study showed that polymeric 2 adopts a distorted octahedral geometry as the carboxylate ligand N,O chelates an Sn atom and at the same time bridges a neighbouring Sn atom via the second O atom, with the remaining sites being occupied by the Cl and two C atoms; the O atoms are trans to each other. The result of the μ2-bridging mode of L- is the formation of a supramolecular helical chain. Compound 4 adopts a skew-trapezoidal bipyramidal geometry with the organo groups lying over the plane of the two N,O-chelating carboxylate ligands and being directed over the weaker Sn-N bonds. The in vitro antimicrobial activities of 1-4 against a Gram-positive bacteria strain (Bacillus subtilis), a Gram-negative bacteria strain (Escherichia coli) and against Candida albicans were studied and compared with the antimicrobial activities of Ph2SnL2 and Me2SnL2, and with the antimicrobial standards gentamicin, tetracycline, ampicillin and penicillin. All organotin compounds displayed remarkable antibacterial activities that were comparable to those of the standard drugs, in particular against B. subtilis, where the activity was correlated with the number of Cl substituents.

Preparation of ethylene-bridged Group 14 metal-zirconocene complexes

The reactions of the zirconocene-ethylene complex Cp2Zr(CH2=CH2)(PMe3) with Group 14 metal chlorides or alkoxides give ethylene-bridged group 14 metal-zirconocene complexes. A reaction mechanism via a five-membered intermediate which involves direct coupling of ethylene and single bonding is proposed.

Reactions of organolanthanide compounds RLnI (Ln = Yb, Eu, Sm) with organic derivatives of silicon, tin, lead, and antimony

Reactions of compounds RLnI (R = Alk, Ar; Ln = Yb, Eu, Sm) with hexaalkyl(aryl)-distannanes, trimethylsilyltriphenyltin, and lead and antimony acetates were studied. The reactions with Sn-Sn and Si-Sn organic derivatives result in cleavage of Sn-Sn amd Sn-Si bonds with formation of tetrasubstituted stannanes and reactive organometallic derivatives with an Sn-Ln or Si-Ln bond. The reactions of RYbI with lead and antimony acetates and with tetraethoxysilane cause cleavage of the Pb-O, Sb-O, or Si-O bond with formation of tetrasubstituted derivatives of lead and silicon or trisubstituted antimony derivatives.
