Organotin compounds and their use for insect and mite control.
نویسنده
چکیده
A brief overview of biological activity of organotin compounds is given, with emphasis on activity against plant-feeding arthropods. Plictran miticide, containing cyhexatin (tricyclohexylhydroxystannane), the first product to be fully commercialized for control of plant-feeding mites on a broad range of agricultural crops, is used as a model to indicate the chemistry and potential performance, phytotoxicity, residues, limitations on usage, environmental acceptability, and use patterns for products containing similar organotin compounds.

Organotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...
متن کاملThe synthesis of some organotin (IV) compounds in the melt- phase
The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...
متن کاملSynthesis and Spectroscopic Characterization of Some New Coordination Compounds of Organotin (IV) with Carbohydrazones
Some new coordination compounds of tin(IV) having general formula [SnBu2 (L)2 ] (where L = carbohydrazone ligand) have been synthesized by the reaction of dibutyltin oxide with carbohydrazone ligands with the ratio of 1:2 (metal- ligand) using dry benzene as a reaction medium. The newly synthesized complexes were characterized by elemental analysis, molecular weight determinations, conductivity...
متن کاملDerivatization methods for the determination of organotin compounds in environmental samples
In the analysis of organotin compounds, derivatization is required in order to achieve more volatile compounds prior to the use of techniques based on GC separation. Derivatization can be considered as one of the main critical steps in organotin analysis, since low yields of derivatization and losses of analytes can easily occur at this stage, and lead to an underestimation of their content in ...
متن کاملPalladium catalyzed coupling of organotin reagents
A novel, synthetically useful palladium catalyzed cross-coupling reaction of organotin reagents with a variety of organic electrophiles that generates a new carbon—carbon bond has been discovered recently. Because this mild, versatile reaction is tolerant of a wide variety of organic functionality on either coupling partner, is stereospecific, and gives high yields, it is ideal for use in the s...
