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-withdra
