Chlorodimethylphenylsilane → Methanesulfonic acid, trifluoro-, dimethylphenylsilyl ester

Participants

Reaction Steps

Phenyldimethylsilyl triflate was prepared by cooling 5 ml of phenyldimethylsilyl chloride to a temperature between 0° and 5° C., and then adding 4.2 ml of trifluoromethanesulfonic acid in a dropwise fashion over a period of about 30 minutes. The resulting mixture was then stirred at a temperature of between 0° and 5° C. for about 6 hours, and subsequently left to stand, with cooling, overnight. The resulting preparation could be used without any further purification.
