Reaction Steps

The fluorinating agent used was N-fluorobenzenesulfonimide obtained from PCR Chemicals (Gainesville Fla.). To a suspension of 0.34 g of NaH in 50 mL of tetrahydrofuran was added 2.45 g of ethylene methanedisulfonate followed by 3.8 g of N-fluorobenzenesulfonimide in 25 mL of acetonitrile. After about 15 min, 25 mL of CH2Cl2 was added, the solution was filtered, and the product was isolated by crystallization from CH2Cl2-cyclohexane to give 0.49 g of ethylene fluoromethanedisulfonate, m.p. 84-86° C. (93-2).
