The quest for silylhydroboranes: (Me(3)Si)(3)SiBH(2).
Reaction of BH(3)·NEt(3) with tris(trimethylsilyl)silylpotassium yielded the respective silylboranate. Abstraction of a hydride with B(C(6)F(5))(3) led to the neutral silylborane, which could be derivatised as an Et(3)N adduct. Treatment of the boranate with Cp(2)Ti(btmsa) resulted in exchange of THF coordinating to potassium by Cp(2)Ti(btmsa).
