Reaction of tertiary cyclopropyl silyl ethers with diethylaminosulfur trifluoride: the effects of substituents on the cleavage of the cyclopropane ring

The reaction of tertiary cyclopropanol silyl ethers with diethylaminosulfur trifluoride usually causes ring opening to produce allylic fluorides. However, cyclopropyl silyl ethers bearing a strong electron-donating substituent at C1 or an electron-withdrawing substituent at C2 do not afford allylic...

Description
Summary:The reaction of tertiary cyclopropanol silyl ethers with diethylaminosulfur trifluoride usually causes ring opening to produce allylic fluorides. However, cyclopropyl silyl ethers bearing a strong electron-donating substituent at C1 or an electron-withdrawing substituent at C2 do not afford allylic fluorides but fluorocyclopropanes. It has also been proved that an electron-donating substituent at C2 of the tertiary cyclopropanol silyl ethers promotes ring opening in the reaction with diethylaminosulfur trifluoride. Graphic
