| 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 (diethylphosphinyl)difluoromethyl]boronic esters. |
| Keywords: | perfluoroalkyl boronic acids and esters perfluoroalkyl trialkoxyborates perfluoroalkyllithium (perfluoroalkyl)trimethylsilane |
