水酸化 トリフェニルすず

使用Triphenyltin Hydroxide is an organotin compound. Triphenyltin Hydroxide is used as a fungicide and antifeeding compound for insect control. Recent studies show that Triphenyltin Hydroxide may have adv erse effects on the reproductive and immune systems and may disrupt the endocrine system.

一般的な説明Odorless white powder. Stable at room temperature. Melting point 121-123°C. Moderately soluble in most organic solvents (Farm Chemical Handbook). Insoluble in water. Non corrosive. Used as a fungicide.

純化方法West, Baney and Powell [J Am Chem Soc 82 6269 1960] purified a sample which was grossly contaminated with tetraphenyltin and diphenyltin oxide by dissolving it in EtOH, most of the impurities remaining behind as an insoluble residue. Evaporation of the EtOH extract gave the crude hydroxide which was converted to triphenyltin chloride (above) by grinding in a mortar under 12M HCl, then evaporating the acidic solution. The chloride, after crystallisation from EtOH, had m 104-105o. It was dissolved in Et2O and converted to the hydroxide by stirring with excess aqueous ammonia. The ether layer was separated, dried, and evaporated to give triphenyltin hydroxide which, after crystallisation from EtOH (or MeCN) and drying under vacuum, was in the form of white crystals (m 119-120o), which retained some cloudiness in the melt above 120o. The hydroxide retains water (0.1-0.5 moles of water per mole) tenaciously. [Glidewell & Liles Acta Cryst (B) 34 129 1978, Beilstein 16 H 914, 16 I 540, 16 II 625, 16 III 1240, 16 IV 1606.]
