Abstract

Lithium and potassium trifluoromethyl-, pentafluoroethyl-and [(diethylphosphinyl) difluoromethyl] trialkoxyborates were synthesized by reaction of either perfluoroalkyllithium or (perfluoroalkyl) trimethylsilane/F− with trialkoxyboranes. Treatment of perfluoroalkyltrialkoxyborates with methanesulfonyl chloride, methyl triflate or methyl tosylate furnished the hitherto unknown trifluoromethyl-, pentafluoroethyl-and [( ...
