実験手順
To a solution of 2-(9-fluorenyl)ethanol 1.26 g, 6 mmol) in 10 ml of toluene and 4 ml of tetrahydrofuran (THF), was added dropwise with stirring phosgene (12.4 ml, 1.93M solution in toluene). The solution was stirred for 0.5 hours, then put under vacuum to remove the phosgene. Concentration yielded 2-(9-fluorenyl)ethyl chloroformate (6 mmol, 1.64 g).
