by-products in the preparations of II and VI, respectively. Reactions of I, II and VII with KOH yield the corresponding salts K[(CF3)3B·NMe2] (IX), K[(CF3)3B·NEt2] (X) and K[(CF3)3B·NHEt] (XI). IX and X react with CH3I, CH3OSO2CF3 and allyl bromide to yield the tertiary amine adducts (CF3)3B·NR1R2R3, R1R2R3Me (XII), R1R2Me, R3C3H5 (XIII), R1R2Et, R3Me (XIV), R1R2Et, R3C3H5 (XV).
