Polymethylhydrosiloxane

폴리(옥시(메틸실릴렌)) C화학적 특성, 용도, 생산

화학적 성질

clear colorless viscous liquid

물리적 성질

colorless free flowing liquid; average molecular weight 1500-2200 g mol?1 (supplier dependent); effective mass per hydride of 60 g mol?1; d = 1.006.

용도

Polymethylhydrosiloxane (PMHS) is an easily handled, inexpensive, non-toxic, and mild reducing agent. Although relatively inert towards organic functionality, PMHS can transfer its hydride to a variety of metal catalysts (including Sn, Ti, Zn, Cu, and Pd) which can then participate in a wide range of reductions. Alternatively, when made hypercoordinate by the action of fluoride or other nucleophiles, PMHS can act directly as a reducing agent. Polymethylhydrosiloxane is widely used as reducing agent often used in conjunction with metal catalysts or nucleophilic activators.

제조 방법

hydrolysis of methyldichlorosilane followed by heating (60–150 °C) the resultant mixture of cyclic silanes in the presence of hexamethyldisiloxane generates the linear polysiloxane.
