Abstract

Reaction of ethylenimine with boron trifluoride at −78° C gives N-β-fluoroethyl-B-difluoroborazene FCH2CH2NHBF2. Acetylation of the latter with acetic anhydride gives N-acetyl-N-β-fluoroethyl-B-difluoroborazene FCH2CH2N(COMe)BF2. The IR spectra of these two compounds are investigated. N-β-fluoroethyl-B-difluoroborazene can react further with ethylenimine to give ultimately a polymeric product with the composition [(FCH2CH2NH)2BF]n which is also obtained by reacting BF3 with excess ethylenimine. Reaction of N-B-fluoroethyl-B-trifluoroborane with triethylamine gives N-triethyl-B-trifluoroborane Et3NBF3.
