Details:

Polymethylhydrosiloxane (PMHS) is a polymer with the general structure -(CH3(H)Si-O)-.
It is used in organic chemistry as a mild and stable reducing agent easily transferring hydrides to metal centers. A variety of related materials are available under the following
These include the tetramer ((MeSiHO)4), copolymers of dimethysiloxane and methylhydrosiloxane, and trimethylsilyl terminated materials.

This material is prepared by the hydrolysis of methyldichlorosilane:

n MeSiHCl2 + n H2O → (MeSiHO)n + 2n HCl

The related polymer polydimethylsiloxane (PDMS) is made similarly, but lacking Si-H bonds, it exhibits no reducing properties.

PMHS is used for in situ conversion of tributyltin oxide to tributyltin hydride:2"(MeSiH)" + (Bu3Sn)2O → "(Me2Si2O" + 2 Bu3SnH .
Polymethylhydrosiloxane (PMHS) - a byproduct of the silicone industry - is a cheap, easy to handle, and environmentally friendly reducing agent. PMHS is more air and moisture stable than other silanes and can be stored for long periods of time without loss of activity.
