| Abstract: | The salts, Ph2B{OCH2CH2N(Me)(CH2)n}2]Ph4B3O3] (n = 4, 5), were prepared in moderate yields in MeOH solution from reaction of Ph2BOBPh2 with N(CH2)n(Me)(CH2CH2OH)]OH] and PhB(OH)2 in a 1:2:4 ratio. The reactions also lead to Ph3B3O3. Both salts were characterized by NMR (1H, 13C, 11B) IR, and single-crystal XRD studies. The salts are comprised of cationic monoborates (zwitterionic, 2N+ and 1B−) and tetraphenylboroxinate anions. |
