RuHCl(CO)(PPh3)3‐Catalyzed Isomerization of Homoallyl Silyl Ethers and Carbonates to Allyl Silyl Ethers and Carbonates

Abstract

AbstractThe selective olefin isomerization of homoallyl silyl ethers and carbonates was studied using RuHCl(CO)(PPh3)3 as a catalyst. While an aryl or alkyl substituent at the α‐position to the oxygen atom caused the selective conversion to allyl silyl ethers, no substituent at the α‐position resulted in the isomerization to enol silyl ethers. In contrast, the isomerization of homoallyl carbonates gave the corresponding allyl carbonates selectively regardless of the substituent at α‐position.magnified image
