Let A and B be two subsets of the set of all non-negative
integers with 0 ε A and O ε B. The sum of the sets A and B is
the set C = A + B = {a + b: a ε A, b ε B). For n...
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...
