Siloxides are chemical compounds with the formula R3SiOM, where R is usually an organic group and M is usually a metal cation. Also called silanoates, they are derived by deprotonation of silanols. They also arise by the degradation of siloxanes by base:〔Clemens Krempner "Role of Siloxides in Transition Metal Chemistry and Homogeneous Catalysis" Eur. J. Inorg. Chem. 2011, 1689–1698. 〕 :R3SiOSiR3 + 2 NaOH → 2 R3SiONa + H2O Cleavage of cyclic siloxanes affords siloxides: :(Me2SiO)3 + MeLi → Me3SiOSiMe2OSiMe2OSiMe2OLi These anions function as ligands for metal ions, forming complexes similar to metal alkoxides. Triphenylsiloxide is a common derivative useful for generating metal complexes. A very bulky siloxide is tert-butyl3SiO−, sometimes called silox. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Siloxide」の詳細全文を読む スポンサード リンク
