Abstract:
A 2,2-bis(fluoroalkyl)oxirane (A) is prepared by reacting a fluorinated alcohol (1) with a chlorinating, brominating or sulfonylating agent under basic conditions to form an oxirane precursor (2) and subjecting the oxirane precursor to ring closure under basic conditions. R1 and R2 are fluoroalkyl groups, R3 and R4 are hydrogen or monovalent hydrocarbon groups, X is chlorine, bromine or —OSO2R5 group, and R5 is alkyl or aryl.
