A large-scale preparative method for potassium di-n-butylborate
in triethylamine solvent has been developed. The reaction of
potassium di-n-butylborate I with trifluoromethyl iodide has been
shown to yield trifluoromethyl di-n-butylborane and other products.
Reaction of this substance with boron trifluoride gave trifluoromethyl
boron difluoride. Reactions of diboron tetrafluoride, boron tribromide,
and...
All attempted synthesis of perfluoroalkyl boron bonded groups
have resulted in the formation of boron-fluorine bonds from the
probable decomposition by α-fluorine transfer. The substance alkali
metal di-n- butylborate (I) has been identified as the potassium derivative
by its reaction with di-n-butylboron chloride and isolation of
potassium chloride. The reaction...
