The first example of the ortho-directing effect of the weakly coordinating substituent [–BF3]– in the catalytic hydrodefluorination of the pentafluorophenyltrifluoroborate anion
Аннотация:
The pentafluorophenyltrifluoroborate anion undergoes hydrodefluorination under the action of zinc in the presence of nickel complexes turning into the 2,3,4,5-tetrafluoroborate anion.
