Sequential homogenous catalysis. Catalytic formation of allylic and β-keto silyl ethers from dihydrosilanes and the corresponding alcohols followed by intramolecular hydrosilation
Abstract
The catalyst, [Rh(Ph2PCH2CH2PPH2)]+ engages in a consecutive catalytic sequence where allylic alcohols, β-keto alcohols and α,β-unsaturated aldehydes in the presence of dihydrosilanes are first converted to the corresponding monohydrosilyl ethers, which are then cyclized.
