Abstract:
A new route to potassium polyfluoroaryltrifluoroborates, K[4-ROC6F4BF3], consisting in the nucleophilic alkoxydefluorination of K[C6F5BF3] with MOR (M = K, Na) in a polar aprotic solvent is suggested. Reaction of K[C6F5BF3] with KO-t-Bu proceeds smoothly at 25 degrees C in DME, but the attempted alkoxydefluorination of K[C6F5BF3] with other NaOR at 30 degrees C in DME failed. A series of K[4-ROC6F4BF3] (R approximate to Me, Et, Pr, i-Pr, Bu, PhCH2) is prepared using the corresponding sodium alkoxides in DMF at 130 degrees C in 80-90% isolated yield. Salt K[4-CH2=CHCH2OC6F4BF3] is prepared at 100 degrees C whereas at 130 degrees C formation of 2,3,5,6-C6F4HOCH2CH=CH2 occurs. Salt K[4-PhOC6F4BF3] is obtained in 82% yield using KOPh (2 equivalents) in DMSO at 130 degrees C.
