化学的特性Triphenylsilane is an off-white solid that is soluble in most organic solvents. It is used in certain cases for the preparation of triphenylsilyl ethers, which serve as alcohol-protecting groups. The triphenylsilyl group is considerably more stable (about 400 times) than the TMS group toward acidic hydrolysis.

調製方法 · 2 件

製造方法Triphenylsilane can be synthesized by reducing phenylsilane (PhSiH3) with a reducing agent such as lithium aluminum hydride (LiAlH4). The overall reaction equation is as follows:3 PhSiH3 + 2 LiAlH4 → C18H16Si + 2 LiH + 2 AlH3This reaction is typically carried out in anhydrous conditions and under inert gas atmosphere.

純化方法Purify it by recrystallisation from MeOH. [Gilman & Zuech J Am Chem Soc 81 5925 1959, Westermark Acta Chem Scand 9 947 1955, IR: Kaplan J Am Chem Soc 76 5880 1954, Beilstein 16 II 605, 16 III 1199, 16 IV 1369.]
