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.폴리(옥시(메틸실릴렌)) 준비 용품 및 원자재
