Description
Poly(methylhydrosiloxane) is a reducing agent. For example, it can be used for the reduction of esters to alcohols as well as the reduction of aldehydes and ketone. It can also be used for the reduction of phosphine oxides to phosphine. Recent study has also used it for conjugate reduction of α, β-Unsaturated Carbonyl and Carboxyl Compounds. Finally, it is also used in greener amine synthesis mediated by reductive amination which is an alternative to borohydrides.Related product price
