Reaction Steps
To a solution of 2.4 g of ethylene methanedisulfonate in 20 mL of THF and 0.35 g of NaH was added 3.8 g of N-fluorobenzene sulfonimide in 25 mL of CH3CN. The product was isolated by crystallization from CH2Cl2 and cyclohexane to give 0.4 g of ethylene fluoromethane disulfonate which was brominated in H2O to give ethylene fluorobromomethanedisulfonate, m.p. 82-90° C. (93-3).
