Ring opening of cyclic ethers by carbonyl chloride fluoride yielded w-chloroalkyl fluoroformates. The reactivity of carbonyl chloride fluoride with cyclic ethers was found to decrease in the order ethylene oxide> trimethylene oxide> tetrahydrofuran> tetrahydropyran. In addition, its reaction with substituted ethylene oxides and butadiene dioxide was investigated. The w-chloroalkyl fluoroformates, a new class of compounds, ...
