Reaction Conditions

Reaction Steps

A reactor flushed with argon gas was cooled with a dry ice-ethanol cooling medium, and 2.03 g (0.0174 mol) of chlorotrifluoroethylene was introduced into the reactor. To this reactor, 17 ml of THF was introduced to bring the chlorotrifluoroethylene concentration to 1 mmol/ml, and then 2.35 g (0.016 mol) of chlorotriethylsilane was added. The reactor was cooled to -78° C., and 12 ml (0.018 mol) of butyllithium (1.47M hexane solution) was added in 1 hour. The mixture was stirred at 78° C. for 4 hours and at room temperature for about 1 hour. Workup was conducted in the same manner as in Example 1, whereby 2.64 g (86.2%) of triethyltrifluorovinylsilane was obtained.
