Abstract
A convenient preparation of K [ArBF3](Ar= 2-C6H4F, 3-C6H4F, 4-C6H4F, 2, 6-C6H3F2, 3, 5- C6H3F2, 2, 4, 6-C6H2F3, 3, 4, 5-C6H2F3, 2, 3, 4, 5-C6HF4 and C6F5) is offered and the IR and multinuclear NMR spectra of these salts are reported. Treatment of the trifluoroborate salts with BF3 in chlorocarbon solvents provides an easy synthetic route to the corresponding aryldifluoroboranes ArBF2. The multinuclear NMR spectra of ArBF2 are ...
